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