CS4952/53

NTSC/PAL Digital Video Encoder

Features

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 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.

Simultaneous composite and S-video output

Supports RS170A and CCIR601 composite

output timing

Multi-standard support for NTSC-M, PAL (B, D,

G, H, I, M, N, Combination N)

Optional progressive scan @ MPEG2 field rates

CCIR656 input mode supporting EAV/SAV

codes and CCIR601 Master/Slave input modes

Stable color subcarrier for MPEG2 systems

NTSC closed caption encoder with interrupt

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.

Supports Macrovision copy protection in
