FEATURES
The PELICAN SAA7112 is a video capture device for
application at the image port of a VGA controller, with
following feature highlights:
Video Decoder
• Six analog inputs, internal analog source selectors,
(e.g. 6 × CVBS or(2 × YC and 2 × CVBS) or
(1 × YC and 4 × CVBS)
• Two analog preprocessing channels, including built in
analog anti-alias filters
• Fully programmable static gain for the main channels or
Automatic Gain Control (AGC) for the selected
CVBS/Y channel
• Two 8 bit video CMOS Analog-to-Digital Converters
(ADCs)
• Automatic Clamp Control (ACC) for CVBS, Y and C
• Switchable white peak control
• On-chip line locked clock generation in accordance with
CCIR-601
• Digital PLL for synchronization and clock generation
from all standards and non-standard video sources,
e.g. consumer grade VTR
• Requires only one crystal (32.11 MHz) for all standards
• Horizontal and vertical sync detection
• Automatic detection of 50/60Hz field frequency, and
automatic switching between standards PAL and NTSC
• Luminance and chrominance signal processing for PAL
BGHI, PAL N, PAL M, NTSC M, NTSC N, NTSC 4.43
and SECAM
• User programmable luminance peaking or aperture
correction
• Cross-colour reduction for NTSC by chrominance
combination filtering
• PAL delay line for correcting PAL phase errors
• Real time status information output (RTCO)
• Independent Brightness Contrast Saturation (BCS)
adjustment for decoder part.
Video Scaler
• Horizontal and vertical down-scaling and up-scaling to
randomly sized windows
• Horizontal and vertical scaling range:
2 (zoom) to1⁄64(icon); vertical zoom might be restricted
• Anti-alias- and accumulating filter for horizontal scaling
SAA7112
• Vertical scaling with linear phase interpolation (6-bit
phase accuracy) and accumulating filter for anti-aliasing
• Horizontal phase correct up- and down-scaling for
improved signal quality of scaled data, especially for
compression and video phone applications, with 6-bit
phase accuracy
• Two independent programming sets for scaler part, to
define two ‘ranges’ per field or per frame
• Field-wise switching between decoder-part and
expansion port input
• Brightness, contrast and saturation controls for scaled
outputs.
VBI-data decoder and text slicer
• versatile VBI-data decoder, slicer, clock regeneration
and byte synchronization; e.g. for WST, NABST, Close
Caption, WSS, etc.
Audio clock generation
• Generation of a field locked audio master clock to
support a constant number of audio clocks per video
field
• Generation of an audio serial and left/right (channel)
clock signal.
Digital I/O interfaces
• Real time signal port (R-port), including continuous line
locked reference clock and real time status information
• Bidirectional expansion port (X-port) with half duplex
functionality (D1), 8-bit YUV
– output from decoder part, real time, or
– input to scaler part, e.g. video from MPEG-decoder
• Video image port (I-port) configurable for 8-bit (16-bit)
data in master mode (own clock), or slave mode
(external clock), with auxiliary timing and hand shake
signals
• 8-bit data Host port (H-port) for 16-bit extension of I-port
• Discontinuous data streams supported
• 32-word × 4 bytes FIFO register for video output data

GENERAL DESCRIPTION
The PELICAN SAA7112 is a video capture device for
applications at the image port of VGA controllers.
The SAA7112 is a combination of a two channel analog
preprocessing circuit including source-selection,
anti-aliasing filter and ADC, an automatic clamp and gain
control, a Clock Generation Circuit (CGC), a digital
multistandard decoder and a SAA7140B based scaler,
including variable horizontal and vertical up and down

SAA7112
scaling and a brightness, contrast and saturation control
circuit (see Fig.1).
It is a highly integrated circuit for desktop video
applications. The decoder is based on the principle of
line-locked clock decoding and is able to decode the colour
of PAL, SECAM and NTSC signals into CCIR-601
compatible colour component values. The SAA7112
accepts as analog inputs CVBS or S-video (Y−C) from TV
or VCR sources, including weak and distorted signals.
An Expansion port for digital video (bidirectional half
duplex, D1 compatible) is also supported to connect to
MPEG or video phone CODEC. At the so called image port
the SAA7112 supports 8-bit (16-bit) wide output data with
auxiliary reference data for interfacing to VGA controllers
The target application for PELICAN is to capture and scale
video images, to be provided as digital video stream
through the image port of a VGA controller, for display via
VGAs frame buffer, or for capture to system memory.
In parallel the SAA7112 incorporates also provisions for
capturing the serially coded data in the vertical blanking
interval (VBI-data). Two principal functions are available:
to capture raw video samples and a versatile data slicer
(data recovery) unit.
The SAA7112 incorporates also a field locked audio clock
generation. This function ensures that there is always the
same number of audio samples associated with a field, or
a set of fields. This prevents the loss of synchronization
between video and audio, during capture or playback.
