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 composite video outputs with high quality of image. 32-pin package and pin assignment make CS8552 compatible with major vendors. w .D a S a t e e h U 4 t .c CS8552 TV Encoder FEATURES Designed special for VCD, Karaoke, digital VCR, DVD, DIGITAL set-top box.
