... GENERAL DESCRIPTION The CS8553 provides full conversion from digital video format YCbCr into NTSC/PAL composite. 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. A 9-bit DAC provides a composite video output with high quality image ...
