Features

Supports ITU-R BT.601 (CCIR601) and Square Pixel 3 Composite Analog Inputs with Sync Tip AGC, Black Clamping and White Peak Control Patented Decoding Scheme with Improved 2-Line Comb Filter, Y/C Separation NTSC M, N, and PAL (B, M, N, CN) Operation Composite or S-Video Input User-Selectable Color Trap and Low Pass Video Filters User Selectable Hue, Saturation, Contrast, Sharpness, and Brightness Controls User Selectable Data Transfer Output Modes 16-Bit 4:2:2 YCbCr 8-Bit 4:2:2 YCbCr User Selectable Clock Range from 30MHz I2C Interface VMI Compatible Video Data Bus

Description

The is a high quality, digital video, color decoder with internal A/D converters. The A/D function includes a 3:1 analog input mux, Sync Tip AGC, Black clamping and two 8-bit A/D Converters. The high quality A/D converters minimize pixel jitter and crosstalk. The decoder function is compatible with NTSC M, PAL M, N and special combination PAL N video standards. Both composite (CVBS) and S-Video (Y/C) input formats are supported. A 2 line comb filter plus a user selectable Chrominance trap filter provide high quality Y/C separation. Various adjustments are available to optimize the image such as Brightness, Contrast, Saturation, Hue and Sharpness controls. Video synchronization is achieved with a 4xfSC chroma burst lock PLL for color demodulation and line lock PLL for correct pixel alignment. A chrominance subsampling 4:2:2 scheme is provided to reduce chrominance bandwidth. The HMP8112 is ideally suited as the analog video interface to VCR's and camera's in any multimedia or video system. The high quality Y/C separation, user flexibility and integrated phase locked loops are ideal for use with today's powerful compression processors. The HMP8112 operates from a single 5V supply and is TTL/CMOS compatible.
