CS8552
CS8552 is TV Encoder manufactured by Myson Technology.
DESCRIPTION w
The CS8552 provides full conversion from digital video format YCb Cr into NTSC/PAL posite and S-video. It can be used in VCD, DVD, and digital VCR applications. Two times oversampling reduces the output filter requirements and guarantees no alias interference by internal UV filters and Y filter. Two 9-bit DACs provide two channels for a Svideo output port or two posite video outputs with high quality image. 32-pin package and pin assignment make the CS8552 patible with major vendors. w w
