HMP8112A

NTSC/PAL Video Decoder

March 1998

Features

Description

• Supports ITU-R BT.601 (CCIR601) and Square Pixel

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.

• 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

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

• 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

a 4xf

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.

• User Selectable Data Transfer Output Modes

• 16-Bit 4:2:2 YCbCr

• 8-Bit 4:2:2 YCbCr

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.

• User Selectable Clock Range from 20MHz - 30MHz

• I C Interface

• VMI Compatible Video Data Bus
