1 / 40 page 1 Semiconductor March 1998 HMP8112A NTSC/PAL Video Decoder 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 and PAL (B, D, G, H, I, 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 20MHz - 30MHz •I2C Interface • VMI Compatible Video Data Bus Applications • Multimedia PCs • Video Conferencing • Video Editing • Video Security Systems • Digital VCRs • Related Products - NTSC/PAL Encoders: HMP8154, HMP8156A, HMP8170/1, HMP8172/3 - NTSC/PAL Decoders: HMP8115, HMP8130/1 Description The HMP8112A 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 B, D, G, H, I, M, N and special combination PAL N video stan- dards. Both composite (CVBS) and S-Video (Y/C) input for- mats 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 sub- sampling 4:2:2 scheme is provided to reduce chrominance bandwidth. The HMP8112A is ideally suited as the analog video inter- face to VCR’s and camera’s in any multimedia or video sys- tem. The high quality Y/C separation, user flexibility and integrated phase locked loops are ideal for use with today’s powerful compression processors. The HMP8112A operates from a single 5V supply and is TTL/CMOS compatible.
