  • SAF7115 Multistandard Video Decoder with Super-Adaptive Comb Filter
    SAF7115 Multistandard video decoder with super-adaptive comb filter, scaler and VBI data read-back via I2C-bus Rev. 01 — 15 October 2008 Product data sheet 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.

The Prior to converting YCbCr data to R´G´B´ data, the 4:2:2 YCbCr color space was developed as part of ITU-R BT.601 YCbCr data must be converted to 4:4:4 YCbCr data.
