.. Advance Information This document contains information on a product under development. The parametric information contains target parameters that are subject to change. Bt829A/827A Video Stream II Decoders Bt829A- Video Capture Processor & Scaler for TV/VCR Analog Input Bt827A- posite Video and S-Video Decoder The Bt829A and Bt827A Video Stream™ Decoders are a family of single-chip, pinand register-patible, posite NTSC/PAL/SECAM video and S-Video decoders. They are also pin and register backward patible with the Bt829/827 family of products. Low operating power consumption and power-down capability make them ideal low-cost solutions for PC video capture applications on both desktop and portable system platforms. They support square pixel and CCIR601 resolutions for NTSC, PAL and SECAM video. They have a flexible pixel port which supports a variety of system interface configurations, and they are offered in 100-pin PQFP and 100-pin TQFP packages.
