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.
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 I
are provided for flexibility in system design. The parallel
interface doubles as a general purpose I/O port when the
CS4952/3 is in I
board area.
