1. General description
The SAF7115 is a video capture device that, due to its improved comb filter performance
and 10-bit video output capabilities, is suitable for various applications such as In-car
video reception, In-car entertainment or In-car navigation.
The SAF7115 is a combination of a two channel analog preprocessing circuit and a high
performance scaler.
The two channel analog preprocessing circuit includes source-selection, an anti-aliasing
filter and Analog-to-Digital Converter (ADC) per channel, an automatic clamp and gain
control, two Clock Generation Circuits (CGC1 and CGC2) and a digital multi standard
decoder that contains two-dimensional chrominance/luminance separation utilizing an
improved adaptive comb filter.
The high performance scaler has variable horizontal and vertical up and down scaling and
a brightness/contrast/saturation control circuit.
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 SAF7115 accepts CVBS or S-video (Y/C) from TV or VCR sources as analog
inputs, including weak and distorted signals.
The expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) can
be used to either output unscaled video using 10-bit or 8-bit dithered resolution or to
connect to other external digital video sources for reuse of the SAF7115 scaler features.
The enhanced image port (I-port) of the SAF7115 supports 8-bit and 16-bit wide output
data with auxiliary reference data for interfacing, e.g. with VGA controller applications. It is
also possible to output video in square pixel formats accompanied by a square pixel clock
of the appropriate frequency.
The SAF7115 also incorporates provisions for capturing the serially coded data in the
Vertical Blanking Interval (VBI-data) of several standards in parallel. Three basic options
are available to transfer the VBI data to other devices:

... NXP Semiconductors The SAF7115 incorporates a frame locked audio clock generation. This function ensures that there is always the same number of audio samples associated with a frame set of fields. This prevents the loss of synchronization between video and audio, during capture or playback. Furthermore, there is an option to use a second analog onboard PLL to enhance this audio clock to a low jitter frame locked audio clock ...
