DS90CF561/DS90CF562
LVDS 18-Bit Color Flat Panel Display (FPD) Link
General Description
The DS90CF561 transmitter converts 21 bits of CMOS/TTL
data into three LVDS (Low Voltage Differential Signaling)
data streams. A phase-locked transmit clock is transmitted in
parallel with the data streams over a fourth LVDS link. Every
cycle of the transmit clock 21 bits of input data are sampled
and transmitted. The DS90CF562 receiver converts the
LVDS data streams back into 21 bits of CMOS/TTL data. At
a transmit clock frequency of 40 MHz, 18 bits of RGB data
and 3 bits of LCD timing and control data (FPLINE, FP-
FRAME, DRDY) are transmitted at a rate of 280 Mbps per
LVDS data channel. Using a 40 MHz clock, the data through-
put is 105 Megabytes per second. These devices are offered
with falling edge data strobes for convenient interface with a
variety of graphics and LCD panel controllers.
