NTSC Picture-In-Picture (PIP) controllerSAB9080
FEATURES
• Double window Picture-In-Picture (PIP) in interlaced or
non-interlaced mode at 8-bit resolution
• Internal 1-Mbit DRAM
• Three 8-bit Analog-to-Digital Converters (ADCs) (7-bit
performance) with clamp circuit for each acquisition
channel
• One PLL which generatesthe line-locked clocks for the
subchannel
• One PLL which generates the line-locked clocks for the
main and display channels
• Three 8-bit Digital-to-Analog Converters (DACs)
• Linear zoom in both horizontal and vertical directions for
the subchannel
• Linear zoom in horizontal direction for the main channel.
The conversion to the digital environment is done on chip
with ADCs. Processing and storage of the video data is
done entirely in the digital domain. The conversion back to
the analog domain is done by DACs.
Internal clocks are generated by PLLs which lock on to the
applied horizontal and vertical syncs.
The main input channel is compressed horizontally by a
factor of two and directly fed to the output. After
compression, a horizontal expansion of two is possible for
the main channel.
The subchannel is also compressed horizontally by a
GENERAL DESCRIPTION
The SAB9080 is an NTSC PIP controller which can be
factor of two but stored in memory before it is fed to the
outputs.
used in double window applications. The SAB9080 inserts
oneortwolivevideosignalswithreducedsizeintoanother
live video signal. The incoming video signals are expected
to be analog baseband signals.

I2C-bus description
The I2C-bus provides bidirectional 2-line communication
between different ICs. The SDA line is the serial data line
and the SCL the serial clock line. Both lines must be
connected to a positive supply via a pull-up resistor when
connected to the output stages of a device.
Data transfer may be initiated only when the bus is not
busy. The SAB9080 has the I2C-bus address 2CH. Valid
subaddresses are 00H to 18H; registers 15H to 18H are
reserved for future extensions.
REPLAY
2
I
C-bus control is according to the I2C-bus protocol: first, a
START sequence must be put on the I2C-bus. Then, the
I2C-bus address of the circuit must be sent, followed by a
subaddress. After this sequence, the data of the
subaddresses must be sent. An auto-increment function
gives the option of sending data of the incremented
subaddresses until a STOP sequence is sent. Table 1
gives an overview of the I2C-bus addresses. The data bits
that are not used should be set to zero.
1999 Nov 127

Table 1 Overview of I2C-bus addresses
For a description of the various data bits, see the following pages.
MPIPON (DOUBLE WINDOW)
Bit MPIPON is used to switch the main channel PIP on
(logic 1) or off (logic 0).
SPIPON
Bit SPIPON is used to switch the subchannel PIPs on
(logic 1) or off (logic 0).
PRIO
Theprioritybitdecideswhetherthe main channel PIP (Prio
set to logic 0) or the subchannel PIP (Prio set to logic 1)
will be on top when both PIPs overlap.
S1FLD
If S1FLD is set to logic 0, two fields are used for the live
PIP.Whena50/60 Hz or a 60/50 Hz mode is detected, the
SAB9080 automatically switches to the 1-Field mode
(1-Field resolution vertically).
If S1FLD is set to logic 1, only one field is used. This
causes joint line errors but saves memory. This bit should
not be set in normal modes.
SFREEZE
SHRED AND SVRED (DOUBLE WINDOW)
Bits SHRed<5:0> and SVRed<6:0> determine the
reduction factors in the double window mode.
Thehorizontal reduction is equal to SHRed/96; the vertical
reduction is equal to SVRed/96. SHRed should lie in the
range from 0 to 48; if set to logic 0, the PIP is off. SVRed
shouldlieintherangefrom0 to 96;ifsettologic 0, the PIP
is off.
When the horizontal reduction factor is 48/96),
704 samples are processed. The horizontal reduction is
linear; therefore, when it is 24/96, 352 samples are
processed.Thesameholdsfor the vertical reduction factor
but then with the number of lines. For NTSC, the number
of processed lines can be calculated from
SVRed/96 × 228 lines.
SHRED AND SVRED (REPLAY)
In replay mode, the ranges of SHRed and SVRed are
limited as follows: SHRed = 12; SVRed = 24, 16 or 12.
This leads to a fixed horizontal reduction factor of1⁄8; and
to a variable vertical reduction factor of1⁄4,1⁄6 or1⁄8.
Note that the resulting replay PIP can be expanded by
using SHBlow and/or SVBlow.
With SFreeze set to logic 1, the current live subchannel
PIP will be frozen. If set to logic 0, it is unfrozen.
ALGOFF
In double window mode, precautions are taken to prevent
a joint line error. Under some conditions, this feature
should be switched off. This can be realized by setting this
bit to logic 1. Normally, bit AlgOff should be set to logic 0.
DNONINT
Innormalmode(thisbit is logic 0), theSAB9080calculates
whether a signal is non-interlaced and reacts accordingly.
With bit DNonint set to logic 1, the display channel is
forced into the non-interlaced mode. In the non-interlaced
mode, only one field is used during the processing of the
PIPs.
PIPMODE
The PIP modes for the SAB9080 are shown in Table 2.
Table 2 PIP modes
PipMode<2:0>MODE

BGHFP AND BGVFP
These bits control the horizontal and vertical positioning of
the PIP configuration on the screen. The horizontal range
is adjustable in 16 steps of four 28 MHz clock periods.
The vertical range is 16 steps of 1 line/field.
The background colour can be adjusted with bits BSel,
SBBrt and SBCol.
SDHFP AND SDVFP
These bytes control the horizontal and vertical positioning
of the subchannel PIPs on the screen. The horizontal
range is 256 steps of eight 28 MHz clock periods.
The vertical range is 256 steps of 1 line/field.
MAHFP, SAHFP AND SAVFP
Bits MAHfp<3:0>, bits SAHfp<3:0> and byte SAVfp
control the horizontal and vertical inset starting-points of
the acquired data. The horizontal range is 16 steps of
eight 28 MHz clock periods when SV2 is set to logic 1.
When SV2 is set to logic 0, the horizontal range is

restricted to eight steps. The vertical range is 256 steps of
1 line/field.
DUVPOL, DVSPOL,DFPOL AND DHSYNC
These bits control the PLL/deflection settings.
With DUVPol, the polarity of the border UV signals can be
inverted when the deflection circuit after the SAB9080
expects inverted signals.
With DVSPol set to logic 0, the SAB9080 triggers on
positive edges of the DVSYNC. If DVSPol is set to logic 1,
it triggers on negative edges. Bit DFPol can invert the
field ID of the incoming fields. Bit DHsync determines the
timing of the DHSYNC pulse. If it is set to logic 0, a
burstkey is expected; if it is set to logic 1, a horizontal sync
is expected at pin DHSYNC.
SUVPOL, SVSPOL, SFPOL AND SHSYNC
ThesebitscontrolthePLL/decodersettings.WithSUVPol,
the polarity of the video UV signals can be inverted when
the decoder circuit before the SAB9080 emits inverted
signals.
With SVSPol set to logic 0, the SAB9080 triggers on
positive edges of the SVSYNC. If it is set to logic 1, it
triggers on the negative edges. Bit SFPol can invert the
field ID of the incoming fields. Bit SHsync determines the
timing of the SHSYNC pulse. If it is set to logic 0, a
burstkey is expected; if it is set to logic 1, a horizontal sync
is expected at pin SHSYNC.
MFIDPON AND SFIDPON
Bits MFidPOn (main field identification position on) and
SFidPOn (subfield identification position on) enable the
field identification position fine tuning. The default value is
off(logic 0), no fine positioning. When on (logic 1), the field
identification position is determined by the value of
bytes MainFidPos and SubFidPos.
100%IRE.Thecolourtypeis one of black (grey), blue, red,
magenta, green, cyan, yellow or white (grey). For black
and white, a finer scale is available.
Bits BSel<1:0> select which colour is set: background or
border, see Table 3.

MDHFP AND MDVFP
These bytes control the horizontal and vertical positioning
of the main PIP on the screen. The horizontal range is
256 steps of eight 28 MHz clock periods. The vertical
range is 256 steps of 1 line/field.
MHRED
Bits MHRed<5:0>, in a range from 0 to 48, determine the
horizontal reduction factor MHRed/96. If they are set to
logic 0, the PIP is off. If they are set to the maximum value
of 48, the horizontal reduction factor is 0.5.
SHBLOW AND SVBLOW (REPLAY MODE)
Bits SHBlow<1:0> and bit SVBlow are used in the replay
mode. These bits can expand a pixel on the display side
by a factor two (01) or four (11) in the horizontal direction
(SHBlow) and a factor of two (1) in the vertical direction
(SVBlow). Zero values indicate no expansion.
MHBLOW
Bit MHBlow can expand the main picture by a factor of two
in the horizontal direction.
BGON
Bit BGOn determines whether the background is visible.
The background has a size of 720 pixels and 240 lines for
NTSC. The background colour can be adjusted with
bits BSel, SBBrt and SBCol.
BON, SBBRT , SBCOL AND BSEL
Bit BOn can switch the sub-borders on (logic 1) or off
(logic 0). Bits SBBrt<1:0> and SBCol<2:0> set the
brightness and colour type of the selected border.
The brightness is set in four levels: 30%, 50%, 70% and
1999 Nov 1210
SLSEL (REPLAY MODE)
In the replay PIP mode, bits SLSel<5:0> determine at
which memory location the PIP data is written, the range
depends on the memory usage for each PIP.
The maximum number of PIPs that can be stored in NTSC
mode is 42.

SDSEL (REPLAY MODE)
Bits SDSel<5:0> select which PIP is read from memory.
Valid numbers are dependent on the maximum value of
SLSel.
SFBLKPKOFF
Bits SFBlkPkOff<1:> shift signals FBL and PKOFF with
respect to the YUV output, by half pixels, see Table 4.

I2CHOLD
Bit I2CHold controls the updating of the I2C-bus controlled
function towards the PIP. If set to logic 1, some updates
are on hold until the bit is set to logic 0. At the next main
Vsync, all settings are passed to the PIP functions.
SV2
When set to logic 0, bit SV2 limits the range of the MAHfp
and SAHfp parameters. Otherwise (bit SV2 set to logic 1),
the parameters have their maximum range (which is
recommended).
HBWIDTH AND VBWIDTH
Bits HBWidth<2:0> and VBWidth<2:0>control the
horizontal and vertical border sizes in steps of two pixels
and one line. The default horizontal border size is four
pixels and the vertical border size is two lines per field.
Default means after power-up and no I2C-bus data sent to
the PIP controller.
NOTES
1. Whentheinputsignalsforthemainand/or subchannel
are non-interlaced, joint line errors can occur. When
non-interlaced signals are input, the SAB9080
switches automatically to the non-interlaced mode.
2. When the prevent joint line error algorithm is switched
off (AlgOff is set to logic 1), joint line errors can still
occur in the 2-Field mode.
The bits and bytes that are on hold when bit I2CHold is set
to logic 1 are:
• MPIPON, SPIPON, DNonint and PipMode
• SHBlow and SVBlow
• SHRed and SVRed
• BGHfp and BGVfp
• SDHfp and SDVfp
• SHPic and SVPic
• BGOn, BOn and Prio
• BSel, SBBrt and SBCol
• SDSel
• MDHfp and MDVfp
• HBWidth and VBWidth.
SV1
Bit SV1 controls the internal horizontal offset of the
background. When set to logic 0, the offset is 0.86 µs;
when set to logic 1, the offset is 4.56 µs.
Acquisition channel ADCs and clamping
Theanaloginputsignalsareconvertedtodigitalsignalsby
three ADCs per channel. The resolution of the ADCs is
8 bits (DNL is 7 bits and INL is 6 bits) and the sampling is
performedatthesystemclockfrequencyof28 MHz for the
Y input. A bias voltage (V
) is used to decouple the AC
bias
components on internal references.
The inputs should be AC coupled and an internal clamp
circuit (using external clamp capacitors) will clamp the
input to a level derived internally from V
ref(B)(MA/SA)
for the
luminancechannelsand,forthechrominancechannels,to
(V
ref(T)(MA/SA)+Vref(B)(MA/SA)
)/2 + LSB/2. The clamping
starts at the active edge of the burst key. Internal video
buffers amplify the standard Y, U and V input signals to
the correct ADC levels.
PLL
The PLL generates an internal system clock from the
f
HSYNC
of 1792 × f
, which is approximately 28 MHz.
HSYNC
DACs and video buffers
The 28 MHz digital video signals are fed to the 8-bit DACs
that produce the required analog video signals. The video
buffers amplify these signals prior to being fed to the
output to drive another device.

SOLDERING
Introduction to soldering surface mount packages
Thistextgivesaverybriefinsightto a complex technology.
A more in-depth account of soldering ICs can be found in
our
“Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
totheprinted-circuitboardbyscreenprinting,stencillingor
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswithleadsonfour sides, the footprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Manual soldering
Wave soldering
Conventional single wave soldering is not recommended
forsurfacemountdevices(SMDs)orprinted-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Suitability of surface mount IC packages for wave and reflow soldering methods
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wavesoldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
