DS90CR583/DS90CR584
LVDS 24-Bit Color Flat Panel Display (FPD) Link—
65 MHz
General Description
The DS90CR583 transmitter converts 28 bits of CMOS/TTL
data into four LVDS (Low Voltage Differential Signaling) data
streams. A phase-locked transmit clock is transmitted in par-
allel with the data streams over a fifth LVDS link. Every cycle
of the transmit clock 28 bits of input data are sampled and
transmitted. The DS90CR584 receiver converts the LVDS
data streams back into 28 bits of CMOS/TTL data. At a trans-
mit clock frequency of 65 MHz, 24 bits of RGB data and 4
bits of LCD timing and control data (FPLINE, FPFRAME,
DRDY, CONTROL) are transmitted at a rate of 455 Mbps per
LVDS data channel. Using a 65 MHz clock, the data through-
put is 227 Mbytes per second. These devices are offered
with rising edge data strobes for convenient interface with a
variety of graphics and LCD panel controllers.
This chipset is an ideal means to solve EMI and cable size
problems associated with wide, high speed TTL interfaces.
