It combines a two channel analog pre-processing circuit and a high performance scaler. The pre-processing circuit includes source selection, an anti-aliasing filter and an analog to digital converter, an automatic clamp and gain control, two clock generation circuits and a digital multi-standard decoder containing two-dimensional chrominance/luminance separation using an improved adaptive comb filter. The high performance scaler features variable horizontal and vertical up and down scaling and a Brightness Contrast Saturation (BCS) control circuit. Based on the principle of line-locked clock decoding, the decoder is able to decode PAL, SECAM and NTSC signals into ITU-601 compatible colour component values. It accepts CVBS or S-Video (Y-C) analog inputs from TV or VCR sources, including weak and distorted signals. The expansion port (X-port) for digital video (bi-directional half duplex, D1 compatible) can be used either to output unscaled video using 10-bit or 8-bit dithered resolution or to connect to other external digital video sources for reuse of the SAA7115's scaler features. An enhanced image port (I-port) supports 8(16)-bit wide output data with auxiliary reference data for interfacing to VGA controllers, set-top box applications, etc. It is also possible to output video in Square Pixel formats accompanied by a square pixel clock of the appropriate frequency. The SAA7115 can capture the serially coded data in the vertical blanking interval (VBI-data) of several broadcast standards. It also incorporates also a frame locked audio clock generation. This ensures that there is always the same number of audio samples associated with a frame or set of fields. This prevents the loss of synchronisation between video and audio, during capture or playback. Furthermore the second analog onboard PLL optionally can be used to enhance this audio clock to a low jitter frame locked audio clock. All the functions of the SAA7115 can be controlled via I2C-bus.
