GENERAL DESCRIPTION
The ADV®7310/ADV7311 is a high speed, digital-to-analog
encoder on a single monolithic chip. It includes six high speed
NSV video D/A converters with TTL compatible inputs.
The ADV7310/ADV7311 has separate 8-/10-/16-/20-bit input
ports that accept data in high definition and/or standard definition
video format. For all standards, external horizontal, vertical,
and blanking signals or EAV/SAV timing codes control the
insertion of appropriate synchronization signals into the digital data stream and therefore the output signal.

PIN CONFIGURATION
The ADV7310/ADV7311 is a Pb-free environmentally friendly
product. It is manufactured using the most up-to-date materials
and processes. The coating on the leads of each device is 100%
pure Sn electroplate. The device is suitable for Pb-free applications, and is able to withstand surface-mount soldering at up to
255°C (±5°C).
In addition it is backward compatible with conventional SnPb
soldering processes. This means that the electroplated Sn coating
can be soldered with Sn/Pb solder pastes at conventional reflow
temperatures of 220°C to 235°C.
*Analog output short circuit to any power supply or common can be of an
indefinite duration.

ADV7310/ADV7311
MPU PORT DESCRIPTION
The ADV7310/ADV7311 support a 2-wire serial (I2C compatible) microprocessor bus driving multiple peripherals. Two inputs,
serial data (SDA) and serial clock (SCL), carry information
between any device connected to the bus and the ADV7310/
ADV7311. Each slave device is recognized by a unique address.
The ADV7310/ADV7311 have four possible slave addresses for
both read and write operations. These are unique addresses for
each device and are illustrated in Figure 17. The LSB sets
either a read or write operation. Logic 1 corresponds to a read
operation, while Logic 0 corresponds to a write operation. A1 is
set by setting the ALSB pin of the ADV7310/ADV7311 to
Logic 0 or Logic 1. When ALSB is set to 1, there is greater
input bandwidth on the I
transfers on this bus. When ALSB is set to 0, there is reduced
input bandwidth on the I

C lines, which allows high speed data

To control the various devices on the bus, the following protocol
must be followed. First the master initiates a data transfer by
establishing a start condition, defined by a high-to-low transition on SDA while SCL remains high. This indicates that
an address/data stream will follow. All peripherals respond to
the start condition and shift the next eight bits (7-bit address +
R/W bit). The bits are transferred from MSB down to LSB. The
peripheral that recognizes the transmitted address responds by
pulling the data line low during the ninth clock pulse. This is
known as an acknowledge bit. All other devices withdraw from
the bus at this point and maintain an idle condition. The idle
condition is where the device monitors the SDA and SCL lines
waiting for the start condition and the correct transmitted address.
The R/W bit determines the direction of the data.
A Logic 0 on the LSB of the first byte means that the master
will write information to the peripheral. A Logic 1 on the LSB
of the first byte means that the master will read information
from the peripheral.
The ADV7310/ADV7311 acts as a standard slave device on
the bus. The data on the SDA pin is 8 bits long, supporting the
7-bit addresses plus the R/W bit. It interprets the first byte as
the device address and the second byte as the starting subaddress.
There is a subaddress auto-increment facility. This allows data
to be written to or read from registers in ascending subaddress
sequence starting at any valid subaddress. A data transfer is
always terminated by a stop condition. The user can also access
any unique subaddress register on a one-by-one basis without
having to update all the registers.
Stop and start conditions can be detected at any stage during the
data transfer. If these conditions are asserted out of sequence
with normal read and write operations, then they cause an
immediate jump to the idle condition. During a given SCL high
period, the user should only issue one start condition, one stop
condition, or a single stop condition followed by a single start
condition. If an invalid subaddress is issued by the user, the
ADV7310/ADV7311 will not issue an acknowledge and will return
to the idle condition. If in auto-increment mode the user exceeds
the highest subaddress, the following action will be taken:
1. In read mode, the highest subaddress register contents
will continue to be output until the master device issues
a no-acknowledge. This indicates the end of a read.
A no-acknowledge condition is when the SDA line is not
pulled low on the ninth pulse.
2. In write mode, the data for the invalid byte will not be loaded
into any subaddress register, a no-acknowledge will be issued
by the ADV7310/ADV7311, and the part will return to the
idle condition.
Before writing to the subcarrier frequency registers, it is a requirement that the ADV7310/ADV7311 has been reset at least once
after power-up.
The four subcarrier frequency registers must be updated, starting
with subcarrier frequency register 0 through subcarrier frequency
register 3. The subcarrier frequency will not update until the last
subcarrier frequency register byte has been received by the
ADV7310/ADV7311.
Figure 19 illustrates an example of data transfer for a write
sequence and the start and stop conditions. Figure 20 shows
bus write and read sequences.

REGISTER ACCESSES
The MPU can write to or read from all of the registers of the
ADV7310/ADV7311 except the subaddress registers, which are
write only registers. The subaddress register determines which
register the next read or write operation accesses. All communications with the part through the bus start with an access to the
subaddress register. A read/write operation is then performed
from/to the target address, which increments to the next address
until a stop command is performed on the bus.
Register Programming
The following tables describe the functionality of each register.
All registers can be read from as well as written to, unless otherwise stated.
Subaddress Register (SR7–SR0)
The communications register is an 8-bit write only register. After
the part has been accessed over the bus and a read/write operation is selected, the subaddress is set up. The subaddress register
determines to/from which register the operation takes place.

INPUT CONFIGURATION
When 10-bit input data is applied, the following bits must be
set to 1:
Address 0x7C, Bit 1 (Global 10-Bit Enable)
Address 0x13, Bit 2 (HD 10-Bit Enable)
Address 0x48, Bit 4 (SD 10-Bit Enable)
Note that the ADV7310 defaults to simultaneous standard
definition and progressive scan on power-up.
Address[01h] : Input Mode = 011
Standard Definition Only
Address[01h] : Input Mode = 000
The 8-/10-bit multiplexed input data is input on Pins S9–S0 (or
Y9–Y0, depending on Register Address 01h, Bit 7), with S0 being
the LSB in 10-bit input mode. Input standards supported are
ITU-R BT.601/656. In 16-bit input mode, the Y pixel data is
input on Pins S9–S2 and CrCb data on Pins C9–C2. The 27 MHz
clock input must be input on Pin CLKIN_A. Input sync signals
are optional and are input on the S_VSYNC, S_HSYNC, andS_BLANK pins.

YCrCb progressive scan, HDTV, or any other HD YCrCb data
can be input in 4:2:2 or 4:4:4. In 4:2:2 input mode, the Y data
is input on Pins Y9–Y0 and the CrCb data on Pins C9–C0. In
4:4:4 input mode, Y data is input on Pins Y9–Y0, Cb data on
Pins C9–C0, and Cr data on Pins S9–S0. If the YCrCb data
does not conform to SMPTE 293M (525p), ITU-R BT.1358M
(625p), SMPTE 274M[1080i], SMPTE 296M[720p], or
BTA-T1004/1362, the async timing mode must be used. RGB
data can only be input in 4:4:4 format in PS input mode only or
HDTV input mode only when HD RGB input is enabled. G data
is input on Pins Y9–Y0, R data on S9–S0, and B data on C9–C0.
The clock signal must be input on Pin CLKIN_A.

YCrCb, PS, HDTV, or any other HD data must be input in
4:2:2 format. In 4:2:2 input mode the HD Y data is input on
Pins Y9–Y0 and the HD CrCb data on C9–C0. If PS 4:2:2 data
is interleaved onto a single 10-bit bus, Y9–Y0 are used for the
input port. The input data is to be input at 27 MHz, with the
data being clocked on the rising and falling edge of the input
clock. The input mode register at Address 01h is set accordingly. If the YCrCb data does not conform to SMPTE 293M
(525p), ITU-R BT.1358M (625p), SMPTE 274M[1080i],
SMPTE 296M[720p], or BTA-T1004, the async timing mode
must be used.
The 8- or 10-bit standard definition data must be compliant
with ITU-R BT.601/656 in 4:2:2 format. Standard definition
data is input on Pins S9–S0, with S0 being the LSB. Using
8-bit input format, the data is input on Pins S9–S2. The clock
input for SD must be input on CLKIN_A and the clock input
for HD must be input on CLKIN_B. Synchronization signals are
optional. SD syncs are input on Pins S_VSYNC, S_HSYNC,
and S_BLANK. HD syncs on Pins P_VSYNC, P_HSYNC,
and P_BLANK.

If in simultaneous SD/HD input mode the two clock phases
differ by less than 9.25 ns or more than 27.75 ns, the CLOCK
ALIGN bit [Address 01h Bit 3] must be set accordingly. If the
application uses the same clock source for both SD and PS, the
CLOCK ALIGN bit must be set since the phase difference
between both inputs is less than 9.25 ns.

YCrCb progressive scan data can be input at 27 MHz or 54 MHz.
The input data is interleaved onto a single 8-/10-bit bus and is
input on Pins Y9–Y0. When a 27 MHz clock is supplied, the data
is clocked in on the rising and falling edge of the input clock and
CLOCK EDGE [Address 0x01, Bit 1] must be set accordingly.
The following figures show the possible conditions: (a) Cb data

TIMING MODES
HD Async Timing Mode
[Subaddress 10h, Bit 3, 2]
For any input data that does not conform to the standards selectable in input mode, Subaddress 10h, asynchronous timing mode
can be used to interface to the ADV7310/ADV7311. Timing control
signals for HSYNC, VSYNC, and BLANK have to be programmed
by the user. Macrovision and programmable oversampling rates
are not available in async timing mode.

other than SMPTE 293M, SMPTE 274M, SMPTE 296M, or
ITU-R BT.1358.
The following truth table must be followed when programming the

HD TIMING RESET
A timing reset is achieved by toggling the HD timing reset control
bit [Subaddress 14h, Bit 0] from 0 to 1. In this state the horizontal
and vertical counters will remain reset. When this bit is set back
to 0, the internal counters will commence counting again.
The minimum time the pin has to be held high is one clock
cycle; otherwise, this reset signal might not be recognized. This
timing reset applies to the HD timing counters only.

SD Real-Time Control, Subcarrier Reset, and Timing Reset
[Subaddress 44h, Bit 2, 1]
Together with the RTC_SCR_TR pin and SD Mode Register 3
[Address 44h, Bit 1, 2], the ADV7310/ADV7311 can be used in
(a) timing reset mode, (b) subcarrier phase reset mode, or (c)
RTC mode.
a. A timing reset is achieved in a low-to-high transition on the
RTC_SCR_TR pin (Pin 31). In this state, the horizontal and
vertical counters will remain reset. On releasing this pin (set
to low), the internal counters will commence counting again,
the field count will start on Field 1, and the subcarrier phase
will be reset.
The minimum time the pin has to be held high is one clock
cycle; otherwise, this reset signal might not be recognized.
This timing reset applies to the SD timing counters only.
b. In subcarrier phase reset, a low-to-high transition on the
RTC_SCR_TR pin (Pin 31) will reset the subcarrier phase to
zero on the field following the subcarrier phase reset when the
SD RTC/TR/SCR control bits at Address 44h are set to 01.

This reset signal will have to be held high for a minimum of
one clock cycle.
Since the field counter is not reset, it is recommended that
the reset signal be applied in Field 7 [PAL] or Field 3 [NTSC].
The reset of the phase will then occur on the next field, i.e.,
Field 1, being lined up correctly with the internal counters.
The field count register at Address 7Bh can be used to identify the number of the active field.
c. In RTC mode, the ADV7310/ADV7311 can be used to lock
to an external video source. The real-time control mode allows
the ADV7310/ADV7311 to automatically alter the subcarrier
frequency to compensate for line length variations. When the
part is connected to a device that outputs a digital data stream
in the RTC format, such as an ADV7183A video decoder
(see Figure 32), the part will automatically change to the
compensated subcarrier frequency on a line by line basis. This
digital data stream is 67 bits wide and the subcarrier is contained in Bits 0 to 21. Each bit is two clock cycles long. 00h
should be written into all four subcarrier frequency registers
when this mode is used.

In fast forward mode, the sync information at the start of a new
field in the incoming video usually occurs before the correct number of lines/fields are reached; in rewind mode, this sync signal
usually occurs after the total number of lines/fields are reached.
Conventionally this means that the output video will have corrupted field signals, one generated by the incoming video and
one generated when the internal lines/field counters reach the
end of a field.
When the VCR FF/RW sync control is enabled [Subaddress 42h
Bit 5] the lines/field counters are updated according to the
incoming VSYNC signal and the analog output matches the
incoming VSYNC signal.
This control is available in all slave timing modes except Slave

Vertical Blanking Interval
The ADV7310/ADV7311 accept input data that contains VBI
data [CGMS, WSS, VITS, and so on] in SD and HD modes.
For SMPTE 293M [525p] standards, VBI data can be inserted
on Lines 13 to 42 of each frame, or on Lines 6 to 43 for the
ITU-R BT.1358 [625p] standard.
For SD NTSC this data can be present on Lines 10 to 20, and
in PAL on Lines 7 to 22.
If VBI is disabled [Address 11h, Bit 4 for HD; Address 43h,
Bit 4 for SD], VBI data is not present at the output and the
entire VBI is blanked. These control bits are valid in all master
and slave modes.
In Slave Mode 0, if VBI is enabled, the blanking bit in the
EAV/SAV code is overwritten, and it is possible to use VBI in
this timing mode as well.
In Slave Mode 1 or 2, the BLANK control bit must be set to
enabled [Address 4Ah, Bit 3] to allow VBI data to pass through
the ADV7310/ADV7311. Otherwise, the ADV7310/ADV7311
automatically blanks the VBI to standard.
If CGMS is enabled and VBI is disabled, the CGMS data will
nevertheless be available at the output.
Subcarrier Frequency Registers
[Subaddress 4Ch–4Fh]
Four 8-bit registers are used to set up the subcarrier frequency.

FILTER SECTION
Table VI shows an overview of the programmable filters available
on the ADV7310/ADV7311.
SD Internal Filter Response
[Subaddress 40h; Subaddress 42, Bit 0]
The Y filter supports several different frequency responses including
two low-pass responses, two notch responses, an extended (SSAF)
response with or without gain boost attenuation, a CIF response,
and a QCIF response. The UV filter supports several different
frequency responses including six low-pass responses, a CIF
response, and a QCIF response, as can be seen in the figures on
the following pages.
If SD SSAF gain is enabled, there is the option of 12 responses
in the range from –4 dB to +4 dB [Subaddress 47, Bit 4]. The
desired response can be chosen by the user by programming the
correct value via the I2C [Subaddress 62h]. The variation of frequency responses can be seen in the figures on the following pages.
In addition to the chroma filters listed in Table VII, the
ADV7310/ADV7311 contains an SSAF filter specifically designed
for and applicable to the color difference component outputs,
U and V. This filter has a cutoff frequency of about 2.7 MHz
and –40 dB at 3.8 MHz, as can be seen in Figure 38. This filter
can be controlled with Address 42h, Bit 0.
If this filter is disabled, the selectable chroma filters shown in
Table VII can be used for the CVBS or Luma/Chroma signal.
Pass-band ripple is the maximum fluctuation from the 0 dB response in the
pass band, measured in dB. The pass band is defined to have 0 Hz to fc (Hz)
frequency limits for a low-pass filter, 0 Hz to f1 (Hz) and f2 (Hz) to infinity for
a notch filter, where fc, f1, and f2 are the –3 dB points.
2
3 dB bandwidth refers to the –3 dB cutoff frequency.

COLOR CONTROLS AND RGB MATRIX
HD Y Level, HD Cr Level, HD Cb Level
[Subaddress 16h–18h]
Three 8-bit registers at Address 16h, 17h, 18h are used to program
the output color of the internal HD test pattern generator, be it
the lines of the cross hatch pattern or the uniform field test
pattern. They are not functional as color controls on external
pixel data input. For this purpose the RGB matrix is used.
The standard used for the values for Y and the color difference
signals to obtain white, black, and the saturated primary and
complementary colors conforms to the ITU-R BT.601-4 standard.
Table VIII shows sample color values to be programmed into
the color registers when Output Standard Selection is set to EIA 770.2.
Table VIII. Sample Color Values for EIA 770.2 Output
Standard Selection
When the programmable RGB matrix is disabled [Address 02h,
Bit 3], the internal RGB matrix takes care of all YCrCb to YUV
or RGB scaling according to the input standard programmed
into the device.
When the programmable RGB matrix is enabled, the color components are converted according to the 1080i standard [SMPTE 274M]:
Y'R'G'B'
=++
0 21260 71520 0722
...
CB'B' Y'
=−−
05 100722
[. /(.)]()
CR'R' Y'
=−−
05 102126
[. /(.)]()
This is reflected in the preprogrammed values for GY = 138Bh,
GU = 93h, GV = 3B, BU = 248h, and RV = 1F0.
If another input standard is used, the scale values for GY, GU,
GV, BU, and RV have to be adjusted according to this input
standard. The user must consider the fact that the color component conversion might use different scale values. For example,
SMPTE 293M uses the following conversion:
Y'R'G'B'
=++
0 2990 5870 114
...
CB'B' Y'
=−−
05 1 0114
[. /(.)]()
CR'R' Y'
=−−
05 1 0299
[. /(. )]()
The programmable RGB matrix can be used to control the HD
output levels in cases where the video output does not conform
to standard due to altering the DAC output stages such as termination resistors. The programmable RGB matrix is used for
external HD data and is not functional when the HD test pattern
is enabled.
REV. A

Programming the RGB Matrix
The RGB matrix should be enabled [Address 02h, Bit 3], the
output should be set to RGB [Address 02h, Bit 5], sync on PrPb
should be disabled [Address 15h, Bit 2], and sync on RGB is
optional [Address 02h, Bit 4].
GY at address 03h and 05h control the output levels on the green
signal, BU at 04h and 08h the blue signal output levels and RV
at 04h and 09h the red output levels. To control YPrPb output
levels, YUV output should be enabled [Address 02h, Bit 5]. In
this case GY [Address 05h; Address 03, Bit 0-1] is used for the
Y output, RV [Address 09; Address 04, Bit 0-1] is used for the
Pr output, and BU [Address 08h; Address 04h, Bit 2-3] is used
for the Pb output.
If RGB output is selected the RGB matrix scaler uses the
following equations:
GGYYGUPb GVPr
=×+×+×
BGYY BUPb
=×+×
RGYY RVPr
=×+×
If YPrPb output is selected the following equations are used:
YGYY
=×
UBUPb
=×
VRVPr
=×
On power-up, the RGB matrix is programmed with the default
values below.

When the programmable RGB matrix is not enabled, the
ADV7310/ADV7311 automatically scales YCrCb inputs to
all standards supported by this part.
SD Luma and Color Control
[Subaddress 5Ch, 5Dh, 5Eh, 5Fh]
SD Y Scale, SD Cr Scale, and SD Cb Scale are three 10-bit
wide control registers to scale the Y, U, and V output levels.
Each of these registers represents the value required to scale the
U or V level from 0.0 to 2.0 and the Y level from 0.0 to 1.5 of
its initial level. The value of these 10 bits is calculated using the
following equation:
Y, U, or V ScalarValue Scale Factor=×512
For example:
Scale Factor = 1.18
Y, U, or V Scale Value
Y, U, or V Scale Value(rounded to the nearest integer)
The hue adjust value is used to adjust the hue on the composite
and chroma outputs.
These eight bits represent the value required to vary the hue of
the video data, i.e., the variance in phase of the subcarrier during
active video with respect to the phase of the subcarrier during
the color burst. The ADV7310/ADV7311 provides a range of
o
22.5
increments of 0.17578125o. For normal operation (zero
adjustment), this register is set to 80h. FFh and 00h represent the
upper and lower limits (respectively) of adjustment attainable.
(Hue Adjust) [
o
] = 0.17578125o × (HCRd – 128), for positive
hue adjust value.
For example, to adjust the hue by +4

The brightness is controlled by adding a programmable setup
level onto the scaled Y data. This brightness level may be added
onto the scaled Y data. For NTSC with pedestal, the setup can
vary from 0IRE to 22.5IRE. For NTSC without pedestal and
PAL, the setup can vary from –7.5IRE to +15IRE.
The brightness control register is an 8-bit register. Seven bits of
this 8-bit register are used to control the brightness level. This
brightness level can be a positive or negative value.
For example:
Standard: NTSC with Pedestal.
To add +20IRE brightness level, write 28h to Address 61h,
SD brightness.
Standard: PAL.
To add –7IRE brightness level, write 72h to Address 61h,
SD brightness.
*Values in the range from 3Fh to 44h might result in an invalid output signal.
SD Brightness Detect
[Subaddress 7Ah]
The ADV7310/ADV7311 allow monitoring of the brightness
level of the incoming video data. Brightness detect is a read-only
register.
Double Buffering
[Subaddress 13h, Bit 7; Subaddress 48h, Bit 2]
Double buffered registers are updated once per field on the
falling edge of the VSYNC signal. Double buffering improves
the overall performance since modifications to register settings
will not be made during active video, but take effect on the start
of the active video.
Double buffering can be activated on the following HD registers:
HD Gamma A and Gamma B curves and HD CGMS registers.
Double buffering can be activated on the following SD registers:
SD Gamma A and Gamma B curves, SD Y Scale, SD U Scale,
SD V Scale, SD Brightness, SD Closed Captioning, and
SD Macrovision Bits 5–0.

In case A, the video output signal is gained. The absolute level
of the sync tip and blanking level both increase with respect to
the reference video output signal. The overall gain of the signal
is increased from the reference signal.
In case B, the video output signal is reduced. The absolute level
of the sync tip and blanking level both decrease with respect to
the reference video output signal. The overall gain of the signal
is reduced from the reference signal.
The range of this feature is specified for ±7.5% of the nominal
output from the DACs. For example, if the output current of
the DAC is 4.33 mA, the DAC tune feature can change this
output current from 4.008 mA (–7.5%) to 4.658 mA (+7.5%).
The reset value of the vid_out_ctrl registers is 00h → nominal
DAC output current. The following table is an example of how
the output current of the DACs varies for a nominal 4.33 mA
output current.
Gamma Correction
[Subaddress 24h–37h for HD, Subaddress 66h–79h for SD]
Gamma correction is available for SD and HD video. For each
standard, there are twenty 8-bit wide registers. They are used to
program the gamma correction curves A and B. HD gamma
curve A is programmed at Addresses 24h to 2Dh, HD gamma
curve B at 2Eh to 7h. SD gamma curve A is programmed at
Addresses 66h to 6Fh, and SD gamma curve B at Addresses
70h to 79h.
Generally gamma correction is applied to compensate for the
nonlinear relationship between signal input and brightness level
output (as perceived on the CRT). It can also be applied wherever
nonlinear processing is used.
Gamma correction uses the function
SignalSignal
=
()
OUTIN
γ
where = gamma power factor.
Gamma correction is performed on the luma data only. The user
may choose either of two different curves, curve A or curve B.
At any one time, only one of these curves can be used.
The response of the curve is programmed at 10 predefined locations. In changing the values at these locations, the gamma curve
can be modified. Between these points, linear interpolation is
used to generate intermediate values. Considering the curve to
have a total length of 256 points, the 10 locations are at 24, 32,
48, 64, 80, 96, 128, 160, 192, and 224. Locations 0, 16, 240,
and 255 are fixed and cannot be changed.
For the length of 16 to 240, the gamma correction curve has to
be calculated as follows:
γ
yx=
where:
y = gamma corrected output
x = linear input signal
= gamma power factor
To program the gamma correction registers, the seven values for
y have to be calculated using the following formula:

HD SHARPNESS FILTER CONTROL AND
ADAPTIVE FILTER CONTROL
[Subaddress 20h, 38h–3Dh]
There are three filter modes available on the ADV7310/ADV7311:
sharpness filter mode and two adaptive filter modes.
HD Sharpness Filter Mode
To enhance or attenuate the Y signal in the frequency ranges
shown in the figures below, the following register settings must
be used: HD sharpness filter must be enabled and HD adaptive
filter enable must be set to disabled.
To select one of the 256 individual responses, the according
gain values for each filter, which range from –8 to +7, must
be programmed into the HD sharpness filter gain register at
Address 20h.
HD Adaptive Filter Mode
The HD adaptive filter threshold A, B, C registers, the HD
adaptive filter gain 1, 2, 3 registers, and the HD sharpness gain
register are used in adaptive filter mode. To activate the adaptive
filter control, the HD sharpness filter must be enabled and HD
adaptive filter enable must be enabled.

The derivative of the incoming signal is compared to the three programmable threshold values: HD adaptive filter threshold A, B, C.
The recommended threshold range is from 16 to 235 although
any value in the range of 0 to 255 can be used.
The edges can then be attenuated with the settings in HD adaptive filter gain 1, 2, 3 registers and HD sharpness filter gain
register.
According to the settings of the HD adaptive filter mode control,
there are two adaptive filter modes available:
1. Mode A is used when adaptive filter mode is set to 0. In this
case, Filter B (LPF) will be used in the adaptive filter block.
Also, only the programmed values for Gain B in the HD sharpness filter gain, HD adaptive filter gain 1, 2, 3 are applied when
needed. The Gain A values are fixed and cannot be changed.
2. Mode B is used when adaptive filter mode is set to 1. In this
mode, a cascade of Filter A and Filter B is used. Both settings for Gain A and Gain B in the HD sharpness filter gain,
HD adaptive filter gain 1, 2, 3 become active when needed.

The HD sharpness filter can be used to enhance or attenuate
the Y video output signal. The following register settings were
used to achieve the results shown in the figures below. Input
data was generated by an external signal source.
The effect of the sharpness filter can also be seen when using
the internally generated cross hatch pattern.

When changing the adaptive filter mode to Mode B [Address 15h,
Bit 6], the following output can be obtained:

The adaptive filter control can also be demonstrated using the
internally generated cross hatch test pattern and toggling the
adaptive filter control bit [Address 15h, Bit 7].
SD Digital Noise Reduction
[Subaddress 63h, 64h, 65h]
DNR is applied to the Y data only. A filter block selects the high
frequency, low amplitude components of the incoming signal
[DNR input select]. The absolute value of the filter output is
compared to a programmable threshold value ['DNR threshold
control]. There are two DNR modes available: DNR mode and
DNR sharpness mode.
In DNR mode, if the absolute value of the filter output is smaller
than the threshold, it is assumed to be noise. A programmable
amount [coring gain border, coring gain data] of this noise
signal will be subtracted from the original signal. In DNR sharpness mode, if the absolute value of the filter output is less than
the programmed threshold, it is assumed to be noise, as before.
Otherwise, if the level exceeds the threshold, now being identified as a valid signal, a fraction of the signal [coring gain border,
coring gain data] will be added to the original signal in order to
boost high frequency components and sharpen the video image.
In MPEG systems, it is common to process the video information
in blocks of 8 pixels × 8 pixels for MPEG2 systems, or 16 pixels ×
16 pixels for MPEG1 systems [block size control]. DNR can be
applied to the resulting block transition areas that are known to
contain noise. Generally, the block transition area contains two
pixels. It is possible to define this area to contain four pixels [border area].
It is also possible to compensate for variable block positioning
or differences in YCrCb pixel timing with the use of the [DNR
block offset].
The digital noise reduction registers are three 8-bit registers.
They are used to control the DNR processing.

Coring Gain Border
[Address 63h, Bits 3–0]
These four bits are assigned to the gain factor applied to
border areas.
In DNR mode, the range of gain values is 0 to 1 in increments
of 1/8. This factor is applied to the DNR filter output, which
lies below the set threshold range. The result is then subtracted
from the original signal.
In DNR sharpness mode, the range of gain values is 0 to 0.5 in
increments of 1/16. This factor is applied to the DNR filter
output, which lies above the threshold range.
The result is added to the original signal.
Coring Gain Data

These four bits are assigned to the gain factor applied to the
luma data inside the MPEG pixel block.
In DNR mode, the range of gain values is 0 to 1 in increments
of 1/8. This factor is applied to the DNR filter output, which
lies below the set threshold range. The result is then subtracted

In DNR sharpness mode, the range of gain values is 0 to 0.5 in

These six bits are used to define the threshold value in the range

[Address 64h, Bit 6]
When this bit is set to a Logic 1, the block transition area can be
defined to consist of four pixels. If this bit is set to a Logic 0,
the border transition area consists of two pixels, where one pixel
refers to two clock cycles at 27 MHz.

Block Size Control
[Address 64h, Bit 7]
This bit is used to select the size of the data blocks to be processed. Setting the block size control function to a Logic 1 defines
a 16 pixel × 16 pixel data block, and a Logic 0 defines an 8 pixel ×
8 pixel data block, where one pixel refers to two clock cycles
at 27 MHz.
DNR Input Select Control
[Address 65h, Bit 2–0]
Three bits are assigned to select the filter, which is applied to
the incoming Y data. The signal that lies in the pass band of
the selected filter is the signal that will be DNR processed.

DNR Mode Control
[Address 65h, Bit 4]
This bit controls the DNR mode selected. A Logic 0 selects
DNR mode; a Logic 1 selects DNR sharpness mode.
DNR works on the principle of defining low amplitude, high
frequency signals as probable noise and subtracting this noise
from the original signal.
In DNR mode, it is possible to subtract a fraction of the signal
that lies below the set threshold, assumed to be noise, from the
original signal. The threshold is set in DNR Register 1.
When DNR sharpness mode is enabled, it is possible to add a
fraction of the signal that lies above the set threshold to the
original signal, since this data is assumed to be valid data and
not noise. The overall effect is that the signal will be boosted
(similar to using Extended SSAF filter).
Block Offset Control
[Address 65h, Bits 7–4]
Four bits are assigned to this control, which allows a shift of the
data block of 15 pixels maximum. Consider the coring gain positions fixed. The block offset shifts the data in steps of one pixel
such that the border coring gain factors can be applied at the
same position regardless of variations in input timing of the data.

Video Output Buffer and Optional Output Filter
Output buffering on all six DACs is necessary in order to drive
output devices, such as SD or HD monitors. Analog Devices
produces a range of suitable op amps for this application, for
example the AD8061. More information on line driver buffering
circuits is given in the relevant op amps’ data sheets.
An optional analog reconstruction low-pass filter (LPF) may be
required as an anti-imaging filter if the ADV7310/ADV7311 is
connected to a device that requires this filtering.
The filter specifications vary with the application.

the excellent noise performance of the ADV7310/ADV7311, it
is imperative that great care be given to the PC board layout.
The layout should be optimized for lowest noise on the ADV7310/
ADV7311 power and ground lines. This can be achieved by
shielding the digital inputs and providing good decoupling.
The lead length between groups of V
DGND, and V
and GND_IO pins should be kept as short
DD_IO
and AGND, VDD and
AA
as possible to minimized inductive ringing.
It is recommended that a 4-layer printed circuit board is used,
with power and ground planes separating the layer of the signal
carrying traces of the components and solder side layer. Component placement should be carefully considered in order to
separate noisy circuits, such as crystal clocks, high speed logic
circuitry, and analog circuitry.
There should be a separate analog ground plane and a separate
digital ground plane.
Power planes should encompass a digital power plane and an
analog power plane. The analog power plane should contain the
DACs and all associated circuitry, V
circuitry. The digital
REF
power plane should contain all logic circuitry.
The analog and digital power planes should be individually
connected to the common power plane at a single point through
a suitable filtering device, such as a ferrite bead.
DAC output traces on a PCB should be treated as transmission
lines. It is recommended that the DACs be placed as close as
possible to the output connector, with the analog output traces
being as short as possible (less than 3 inches). The DAC termination resistors should be placed as close as possible to the DAC
outputs and should overlay the PCB’s ground plane. As well as
minimizing reflections, short analog output traces will reduce
noise pickup due to neighboring digital circuitry.
To avoid crosstalk between the DAC outputs, it is recommended
that as much space as possible be left between the tracks of the
individual DAC output pins. The addition of ground tracks
between outputs is also recommended.
Supply Decoupling
Noise on the analog power plane can be further reduced by the
use of decoupling capacitors.
Optimum performance is achieved by the use of 10 nF and
0.1 µF ceramic capacitors. Each group of V
, VDD, or V
AA
DD_IO
pins should be individually decoupled to ground. This should
be done by placing the capacitors as close as possible to the
device with the capacitor leads as short as possible, thus minimizing lead inductance.
A 1 µF tantalum capacitor is recommended across the V
AA
supply in addition to 10 nF ceramic.
See the circuit layout in Figure 61.
Digital Signal Interconnect
The digital signal lines should be isolated as much as possible
from the analog outputs and other analog circuitry. Digital
signal lines should not overlay the analog power plane.
Due to the high clock rates used, long clock lines to the
ADV7310/ADV7311 should be avoided to minimize noise
pickup.
Any active pull-up termination resistors for the digital inputs
should be connected to the digital power plane and not the
analog power plane.
Analog Signal Interconnect
The ADV7310/ADV7311 should be located as close as possible
to the output connectors, thus minimizing noise pickup and
reflections due to impedance mismatch.
For optimum performance, the analog outputs should each
be source and load terminated, as shown in Figure 61. The
termination resistors should be as close as possible to the
ADV7310/ADV7311 to minimize reflections.
For optimum performance, it is recommended that all decoupling
and external components relating to the ADV7310/ADV7311
be located on the same side of the PCB and as close as possible
to the ADV7310/ADV7311.
Any unused inputs should be tied to ground.

APPENDIX 1—COPY GENERATION
MANAGEMENT SYSTEM
PS CGMS Data Registers 2–0
[Subaddress 21h, 22h, 23h]
PS CGMS is available in 525p mode conforming to CGMS-A
EIA-J CPR1204-1, transfer method of video ID information using
vertical blanking interval (525p system), March 1998, and
IEC61880, 1998, Video systems (525/60)—video and accompanied data using the vertical blanking interval—analog interface.
When PS CGMS is enabled [Subaddress 12h, Bit 6 = 1], CGMS
data is inserted on line 41. The PS CGMS data registers are at
Addresses 21h, 22h, and 23h.
SD CGMS Data Registers 2–0
[Subaddress 59h, 5Ah, 5Bh]
The ADV7310/ADV7311 supports Copy Generation Management System (CGMS), conforming to the standard. CGMS
data is transmitted on Line 20 of the odd fields and Line 283 of
even fields. Bits C/W05 and C/W06 control whether or not
CGMS data is output on odd and even fields. CGMS data can
be transmitted only when the ADV7310/ADV7311 is configured
in NTSC mode. The CGMS data is 20 bits long, and the function of each of these bits is as shown in the following table. The
CGMS data is preceded by a reference pulse of the same amplitude and duration as a CGMS bit; see Figure 63.
HD/PS CGMS [Address 12h, Bit 6]
The ADV7310/ADV7311 supports Copy Generation Management
System (CGMS) in HDTV mode (720p and 1080i) in accordance with EIAJ CPR-1204-2.
The HD CGMS data registers are to be found at address 021h,
22h, 23h.

CGMS data is applied to Line 24 of the luminance vertical
blanking interval.
1080i System
CGMS data is applied to Line 19 and on Line 582 of the luminance vertical blanking interval.
CGMS Functionality
If SD CGMS CRC [Address 59h, Bit 4] or PS/HD CGMS CRC
[Subaddress 12h, Bit 7] is set to a Logic 1, the last six bits,
C19–C14, which comprise the 6-bit CRC check sequence, are
calculated automatically on the ADV7310/ADV7311 based on
the lower 14 bits (C0–C13) of the data in the data registers and
output with the remaining 14 bits to form the complete 20 bits
of the CGMS data. The calculation of the CRC sequence is
based on the polynomial x
6
+ x + 1 with a preset value of 111111.
If SD CGMS CRC [Address 59h, Bit 4] and PS/HD CGMS
CRC [Address 12h, Bit 7] is set to a Logic 0, all 20 bits (C0–C19)
are output directly from the CGMS registers (no CRC is calculated, must be calculated by the user).
The ADV7310/ADV7311 support wide screen signaling (WSS)
conforming to the standard. WSS data is transmitted on Line 23.
WSS data can be transmitted only when the device is configured
in PAL mode. The WSS data is 14 bits long, and the function
of each of these bits is shown in Table XIX. The WSS data is
preceded by a run-in sequence and a start code; see Figure 66.
If SD WSS [Address 59h, Bit 7] is set to a Logic 1, it enables the
WSS data to be transmitted on Line 23. The latter portion of
Line 23 (42.5 µs from the falling edge of HSYNC) is available for
the insertion of video.
It is possible to blank the WSS portion of Line 23 with
Subaddress 61h, Bit 7.

The ADV7310/ADV7311 support closed captioning conforming
to the standard television synchronizing waveform for color
transmission. Closed captioning is transmitted during the blanked
active line time of Line 21 of the odd fields and Line 284 of the
even fields.
Closed captioning consists of a 7-cycle sinusoidal burst that is
frequency and phase locked to the caption data. After the clock
run-in signal, the blanking level is held for two data bits and is
followed by a Logic 1 start bit. Sixteen bits of data follow the
start bit. These consist of two 8-bit bytes, seven data bits, and
one odd parity bit. The data for these bytes is stored in the SD
closed captioning registers [Address 53h–54h].
The ADV7310/ADV7311 also support the extended closed
captioning operation, which is active during even fields and is
encoded on Scan Line 284. The data for this operation is stored
in the SD closed captioning registers [Address 51h–52h].
All clock run-in signals and timing to support closed captioning
on Lines 21 and 284 are generated automatically by the ADV7310/

ADV7311. All pixels inputs are ignored during Lines 21 and
284 if closed captioning is enabled.
FCC Code of Federal Regulations (CFR) 47 section 15.119
and EIA608 describe the closed captioning information for
Lines 21 and 284.
The ADV7310/ADV7311 use a single buffering method. This
means that the closed captioning buffer is only 1-byte deep;
therefore there will be no frame delay in outputting the closed
captioning data unlike other 2-byte deep buffering systems. The
data must be loaded one line before (Line 20 or Line 283) it is
output on Line 21 and Line 284. A typical implementation of this
method is to use VSYNC to interrupt a microprocessor, which
in turn will load the new data (two bytes) in every field. If no
new data is required for transmission, 0s must be inserted in
both data registers; this is called nulling. It is also important to
load control codes, all of which are double bytes on Line 21, or
a TV will not recognize them. If there is a message like “Hello
World” that has an odd number of characters, it is important to
pad it out to even in order to get “end of caption” 2-byte control
code to land in the same field.

blank lines as per CCIR-624. HSYNC is output in master mode
and input in slave mode on S_VSYNC, BLANK on S_BLANK,
and VSYNC on S_VSYNC.
