parameters that are subject to change.
Bt829B/827B
VideoStreamII Decoders
Bt829B– Video Capture Processor and Scaler for
TV/VCR Analog Input
Bt827B– Composite Video and S-Video Decoder
The Bt829B and Bt827B VideoStream™ Decoders are a family of single-chip, pin-
and register-compatible, composite NTSC/PAL/SECAM video and S-Video decod-
ers. They are also pin and register backward compatible with the Bt829A/827A
family of products. Low operating power consumption and power-down capabil-
ity make them ideal low-cost solutions for PC video capture applications on both
desktop and portable system platforms with a 3.3 V digital I/O interface. 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 config-
urations, and they are offered in a 100-pin Plastic Quad Flat Pack (PQFP).
