Input formats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or CCIR656 with sup- port for EAV/SAV codes. Output video can be formatted to be compatible with NTSC-M, or PAL B,D,G,H,I,M,N, and Combination N systems. Also supported is NTSC line 21 and line 284 closed captioning encoding. Four 9-bit DACs provide two channels for an S-Video out- put port and two composite video outputs. 2x oversampling reduces the output filter requirements and guarantees no DAC related modulation components within the spec- ified bandwidth of any of the supported video standards. Parallel or high speed I2C compatible control interfaces are provided for flexibility in system design. The parallel interface doubles as a general purpose I/O port when the CS4952/3 is in I2C mode to help conserve valuable board area.
