Description

The CS4952/3 provides full conversion from YCbCr or YUV digital video formats into NTSC & PAL Composite and Y/C (S-video) analog video. Input formats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or CCIR656 with support 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 CS4953 provide two channels for an S-Video output port and two composite video outputs. 2x oversampling reduces the output filter requirements and guarantees no DAC related modulation components within the specified 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.
