General description
The SAF7118 is a video capture device that, due to its improved comb filter performance,
is suitable for various applications such as in-car video reception, in-car entertainment or
in-car navigation.
The SAF7118 is a combination of a four-channel analog preprocessing circuit including
source selection, anti-aliasing filter and Analog-to-Digital Converter (ADC) with
succeeding decimation filters from 27 MHz to 13.5 MHz data rate. Each preprocessing
channel comes with an automatic clamp and gain control. The SAF7118 combines a
Clock Generation Circuit (CGC), a digital multistandard decoder containing
two-dimensional chrominance/luminance separation by an adaptive comb filter and a high
performance scaler, including variable horizontal and vertical up and downscaling and a
brightness, contrast and saturation control circuit.
It is a highly integrated circuit for desktop video and similar applications. The decoder is
based on the principle of line-locked clock decoding and is able to decode the color of
PAL, SECAM and NTSC signals into ITU 601 compatible color component values. The
SAF7118 accepts CVBS or S-video (Y/C) as analog inputs from TV or VCR sources,
including weak and distorted signals as well as baseband component signals Y-P
B
-P
R
or
RGB. An expansion port (X port) for digital video (bidirectional half duplex, D1 compatible)
is also supported to connect to MPEG or a video phone codec. At the so called image port
(I port) the SAF7118 supports 8-bit or 16-bit wide output data with auxiliary reference data
for interfacing to VGA controllers.
The target application for the SAF7118 is to capture and scale video images, to be
provided as a digital video stream through the image port of a VGA controller, for capture
to system memory, or just to provide digital baseband video to any picture improvement
processing.
The SAF7118 also provides a means for capturing the serially coded data in the Vertical
Blanking Interval (VBI) data. Two principal functions are available:
1. To capture raw video samples, after interpolation to the required output data rate, via
the scaler
2. A versatile data slicer (data recovery) unit
The SAF7118 also incorporates 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.
All of the ADCs may be used to digitize a Vestigial Side Band (VSB) signal for subsequent
decoding; a dedicated output port and a selectable VSB clock input is provided.
