Bt827A– Composite Video and S-Video Decoder

The Bt829A and Bt827A 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 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.
