Description

The CS4952-CL is an electronic component model in the IC Chips product category. It provides full conversion from YCbCr or YUV digital video formats into NTSC & PAL Composite and Y/C (S-video) analog video. The input formats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or CCIR656 with support for EAV/SAV codes. The output video can be formatted to be compatible with NTSC-M, or PAL B, D, G, H, I, M, N, and Combination N systems. Additionally, it supports NTSC line 21 and line 284 closed captioning encoding.
