Description
The CS4954/5 provides full conversion from digital video
formats YCbCr or YUV to NTSC and PAL Composite,
Y/C (S-video) and RGB, or YUV analog video. Input for-
mats can be 27 MHz 8-bit YUV, 8-bit YCbCr, or ITU
R.BT656 with support for EAV/SAV codes. Video output
can be formatted to be compatible with NTSC-M, NTSC-
J, PAL-B,D,G,H,I,M,N, and Combination N systems.
Closed Caption is supported in NTSC. Teletext is sup-
ported for NTSC and PAL.
Six 10-bit DACs provide two channels for an S-Video
output port, one or two composite video outputs, and
three RGB or YUV outputs. Two-times oversampling re-
duces the output filter requirements and guarantees no
DAC-related modulation components within the speci-
fied 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 CS4954/5 is
in I2C mode to help conserve valuable board area.
The CS4954 and CS4955 are available in a 48-pin TQFP
and operate in -40 to +85°C ambient temperature. The
CDB4954/55 Customer Demonstration board is also
available. Please refer to
