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 parallel 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 transmit 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 throughput
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.
