IC801
DVP-M2
RH-iXB882WJZZQ
DVP-M2 is 1 chip picture signal processing LSI for flat panel displays
corresponding to a multi-format (NATC/PAL/SECAM). A 10-bit A/D
converter is mounted as an analog image input, and it has the input
terminal of one CVBS, Y/C, Y/Pb/Pr, one R/G/B input each, and one
SCART input. In a picture signal processing part, a high definition
image is made by three-dimensional adaptation type Y/C separation
and motion adaptation three-dimensional NR conversion. DVP-M 2S
builds in 64 M bit SDRAM as a buffer memory, the microcomputer for
system control (32/16 bit), 1024 K bytes of flash memory, and the
sound multiplex decoder, and constitutes the system from small num-
ber of parts.

RSDS-transmitter RH-iXC209WJZZQ
IXC209WJ (LR38875) is a RSDS transmitter for LCD controllers.
LVDS RGB 8bit data and a clock signal are changed and outputted to
RSDS. A RSDS output is a differential output of data output 12 pair
+CLK output 1 pair, and a data rate corresponds to 180Mbps
(=90MHz). Connection with the RSDS panel is enabled by using it
between the LCD panel of a RSDS interface and the LCD timing con-
trollers of a CMOS output, without changing the existing system.
