GENERAL DESCRIPTION

The ADV®7314 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 ADV7314 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.

MPU PORT DESCRIPTION

The ADV7314 supports 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. Each slave device is recognized by a unique address. The ADV7314 has 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 ADV7314 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 less than 50 ns will not pass into the I

Figure 17. ADV7314 Slave Address = D4h
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 when 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 ADV7314 acts as a standard slave device on the bus. The data on the SDA pin is eight bits wide, 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, which 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 these cause an immediate jump to the idle condition. During a given SCL high period, the user should issue only 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 ADV7314 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 ADV7314, and the part will return to the idle condition.

ADV7314
Before writing to the subcarrier frequency registers, the ADV7314 must have been reset at least once since 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 ADV7314.
Figure 18 illustrates an example of the data transfer for a write sequence and the start and stop conditions.
Figure 19 shows bus write and read sequences.

REGISTER ACCESS

The MPU can write to or read from all of the registers of the ADV7314 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 on the bus is performed.

Register Programming

The following section describes 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 ADV7314 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-bit/10-bit multiplexed input data is input on Pins S9–S0 (or Y9–Y0, depending on Register Address 0x01, Bit7), 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 is input on Pins C9–C2. The 27 MHz clock input must be input on the CLKIN_A pin.
Input sync signals are optional and are input on the S_VSYNC, S_ HSYNC, and S_BLANK pins.

Progressive Scan Only or HDTV Only Address [01h] Input Mode 001 or 010, Respectively
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 T-1004/1362, the async timing mode must be used.
RGB data can be input in 4:4:4 format in PS Input mode only or in 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 the CLKIN_A pin.

Simultaneous Standard Definition and Progressive Scan or HDTV Address [01h]: Input Mode 011(SD 40-Bit, PS 20-Bit) or 101 (SH and HD, SD Oversampled), 110 (SD and HD, HD Oversampled)
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 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 T-1004, the Async Timing mode must be used.
The 8-bit or 10-bit standard definition data must be compliant to 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 are input on Pins P_VSYNC, P_ HSYNC, P_BLANK.

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 01h, asynchronous tim­ing mode can be used to interface to the ADV7314. 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. When using async mode, the PLL must be turned off [Subaddress 00h, Bit 1 = 1].
Figures 28a and 28b show an example of how to program the ADV7314 to accept a different high definition standard other than SMPTE 293M, SMPTE 274M, SMPTE 296M, or ITU-R BT.1358. The truth table in Table V must be followed when programming the control signals in async timing mode.

*When async timing mode is enabled, P_BLANK [Pin 25] becomes an active high input. P_BLANK is set to active low at Address 10h, Bit 6.
For standards that do not require a tri-sync level, P_BLANK must be tied low at all times.
HD Timing Reset [Subaddress 14h, Bit 0]
A timing reset is achieved in setting the HD timing reset control bit at Address 14h from 0 to 1. In this state, the horizontal and vertical counters will remain reset. On setting this bit 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, the ADV7314 can be used in timing reset mode, subcarrier phase reset mode, or RTC mode.
Timing Reset Mode
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.
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.

NO TIMING RESET APPLIED

313 320
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 should 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.
RTC Mode
In RTC mode, the ADV7314 can be used to lock to an external video source. The real-time control mode allows the ADV7314 to automatically alter the subcarrier frequency to compensate for line length variations. When the part is connected to a device that outputs a digital datastream in the RTC format (such as an ADV7183A video decoder, see Figure 31), the part will auto­matically change to the compensated subcarrier frequency on a line by line basis. This digital datastream 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 using this mode.

Reset Sequence

A reset is activated with a high-to-low transition on the RESET pin [Pin 33] according to the timing specifications. The ADV7314 will revert to the default output configuration. Figure 32 illus­trates the RESET sequence timing.
SD VCR FF/RW Sync [Subaddress 42h, Bit 5]
In DVD record applications where the encoder is used with a decoder, the VCR FF/RW Sync control bit can be used for non­standard input video, i.e., in fast forward or rewind modes.
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/field are reached. In rewind mode, this sync

signal usually occurs after the total number of lines/field are reached. Conventionally this means that the output video will have corrupted field signals, one generated by the incoming video and one 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 Mode 0.

Vertical Blanking Interval

The ADV7314 accepts input data that contains VBI data [e.g., CGMS, WSS, VITS] in SD and HD modes.
For SMPTE 293M [525p] standards, VBI data can be inserted on Lines 13 to 42 of each frame, or Lines 6 to 43 for 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; 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 ADV7314; otherwise the ADV7314 automatically blanks the VBI to standard.
If CGMS is enabled and VBI is disabled, the CGMS data will nevertheless be available at the output.

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 Typical Performance Characteristics graphs.
If SD SSAF gain is enabled, there are 12 possible responses in the range from –4 dB to +4 dB [Subaddress 47h, 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 Typical Performance Characteristics graphs.

Pass-band ripple refers to the maximum fluctuations 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, f2 are the –3 dB points.
2
3 dB bandwidth refers to the –3 dB cutoff frequency.
In addition to the chroma filters listed in Table VII, the ADV7314 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 37. 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.

COLOR CONTROLS AND RGB MATRIX

HD/PS Y Level, Cr Level, 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, whether it is 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.

HD RGB Matrix [Subaddress 03h–09h]
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' = 0.2126R' + 0.7152 G' + 0.0722 B' CR' = [0.5/(1 – 0.0722)] (B'–Y') CR' = [0.5/(1 – 0.2126)] (R'–Y')
This is reflected in the preprogrammed values for GY = 138Bh, GU = 93h, GV = 3B, BU = 248h, 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 that the color component conversion might use different scale values. For example, SMPTE 293M uses the following conversion:
Y' = 0.299 R' + 0.587 G' + 0.114 B' CB' = [0.5 / (1 – 0.114)] (B'–Y') CR' = [0.5 / (1 – 0.299)] (R'–Y')
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.

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], sync on RGB is optional [Address 02h, Bit 4].
GY at Addresses 03h and 05h control the output levels on the green signal, BU at 04h and 08h control the blue signal output levels, and RV at 04h and 09h control 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:
G = GY Y + GU Pb + GV Pr B = GY Y + BU Pb R = GY Y + RV Pr
If YUV output is selected the following equations are used:
Y = GY  Y
U = BU  Pb
V = RV  Pr
On power-up, the RGB matrix is programmed with default values:
Table IX. RGB Matrix Default Values
Address Default
03h 03h 04h F0h 05h 4Eh 06h 0Eh 07h 24h 08h 92h 09h 7Ch
When the programmable RGB matrix is not enabled, the ADV7314 automatically scales YCrCb inputs to all standards supported by this part.
SD Luma and Color Control [Subaddresses 5Ch, 5Dh, 5Eh, 5Fh]
SD Y scale, SD Cr scale, and SD Cb scale are 10-bit 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 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 Scalar Value = Scale Factor 512
For example:
Scale Factor = 1.18
Y, U, or V Scale Value = 1.18 512 = 665.6 Y, U, or V Scale Value = 665 (rounded to the nearest integer) Y, U, or V Scale Value = 1010 0110 01b

SD Hue Adjust Value [Subaddress 60h]
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 ADV7314 provides a range of ±22.5incre­ments of 0.17578125. For normal operation (zero adjustment), this register is set to 80h. FFh and 00h represent the upper and lower limit (respectively) of adjustment attainable.

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 0 IRE to 22.5 IRE. For NTSC without pedestal and PAL, the setup can vary from –7.5 IRE to +15 IRE.
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:

The ADV7314 allows 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. Table XI 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 20 8-bit registers. They are used to program the gamma correction curves A and B. HD gamma curve A is programmed at Addresses 24h–2Dh, HD gamma curve B at 2Eh–37h. SD gamma curve A is programmed at addresses 66h–6Fh, and SD gamma curve B at Addresses 70h–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
Signal Signal
=
()
OUT IN
g
where = gamma power factor.
Gamma correction is performed on the luma data only. The user has the choice to use two different curves, curve A or curve B. At any 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. Location 0, 16, 240, and 255 are fixed and cannot be changed.

HD Sharpness Filter Control and Adaptive Filter Control [Subaddress 20h, 38h–3Dh]
There are three Filter modes available on the ADV7314: 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 Figure 42, the following register settings must be used: HD sharpness filter must be enabled and HD adaptive filter enable must be 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 filter gain register are used in adaptive filter mode. To activate the adaptive filter control, HD sharpness filter must be enabled and HD adaptive filter gain must be enabled.

FILTER A RESPONSE (Gain Ka)
Figure 42. Sharpness and Adaptive Filter Control Block Frequency Response in Sharpness Filter Mode with Ka = +3 and Kb = +7
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 gain 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.

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 to 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 0–1, 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 0–0.5, 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 [Address 63h, Bits 7-4]

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 0–1, 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 0–0.5, 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.

These six bits are used to define the threshold value in the range of 0 to 63. The range is an absolute value.

Border Area [Address 64h, Bit 6]

In setting this bit 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; 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 that 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. Figure 50 shows the filter responses selectable with this control.

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.

SD ACTIVE VIDEO EDGE [Subaddress 42h, Bit 7]
When the active video edge is enabled, the first three pixels and the last three pixels of the active video on the luma channel are scaled in such a way that maximum transitions on these pixels are not possible. The scaling factors are ¥1/8, ¥1/2, ¥7/8. All other active video passes through unprocessed.

The ADV7314 can control fast rising and falling signals at the start and end of active video to minimize ringing.
An algorithm monitors SAV and EAV and governs when the edges are too fast. The result will be reduced ringing at the start and end of active video for fast transitions.

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 amp data sheets.
An optional analog reconstruction low-pass filter (LPF) may be required as an anti-imaging filter if the ADV7314 is connected to a device that requires this filtering. The filter specifications vary with the application.

ADV7314

PC BOARD LAYOUT CONSIDERATIONS

The ADV7314 is optimally designed for lowest noise perfor­mance, for both radiated and conducted noise. To complement the excellent noise performance of the ADV7314, it is impera­tive that great care be given to the PC board layout.
The layout should be optimized for lowest noise on the ADV7314 power and ground lines. This can be achieved by shielding the digital inputs and providing good decoupling. The lead length between groups of V
and GND_IO pins should be kept as short as possible to
V
DD_IO
and AGND, VDD and DGND, and
AA
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 one 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 to leave as much space as possible 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 mF ceramic capacitors. Each of 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 mF tantalum capacitor is recommended across the V
supply
AA
in addition to a 10 nF ceramic capacitor. See Figure 60.

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 ADV7314 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 to the analog power plane.

Analog Signal Interconnect

The ADV7314 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 60. The termi­nation resistors should be as close as possible to the ADV7314 to minimize reflections.
For optimum performance, it is recommended that all decoupling and external components relating to the ADV7314 be located on the same side of the PCB and as close as possible to the ADV7314.
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 ADV7314 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 ADV7314 is configured in NTSC mode. The CGMS data is 20 bits long, and the function of each of these bits is as shown in Table XVIII. The CGMS data is preceded by a reference pulse of the same amplitude and duration as a CGMS bit; see Figure 62.

HD/PS CGMS [Address 12h, Bit 6]

The ADV7314 supports Copy Generation Management System (CGMS) in HDTV mode (720p and 1080i) in accordance with EIAJ CPR-1204-2.
The HD CGMS data registers can be found at Address 021h, 22h, 23h.

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 ADV7314 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] or 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 calculated, must be calculated by the user).

APPENDIX 2—SD WIDE SCREEN SIGNALING [Subaddress 59h, 5Ah, 5Bh]
The ADV7314 supports wide screen signaling (WSS) conforming to the standard. WSS data is transmitted on Line 23. WSS data can be transmitted only when the ADV7314 is configured in PAL mode. The WSS data is 14 bits long, and the function of each of these bits is as shown in Table XIX. The WSS data is preceded

APPENDIX 3—SD CLOSED CAPTIONING [Subaddress 51h–54h]
The ADV7314 supports 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 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 Level 1 start bit. 16 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 ADV7314 also supports 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 ADV7314. 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 ADV7314 uses a single buffering method. This means that the closed captioning buffer is only one byte deep, therefore there will be no frame delay in outputting the closed captioning data unlike other two 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) every field. If no new data is required for transmission, 0s must be inserted in both data registers, which is called nulling. It is also important to load control codes, all of that are double bytes on Line 21 or a televi­sion 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.
