LVDS Transmitter 24-Bit Color Flat Panel Display (FPD)
Link
General Description
The DS90CF581 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. At a transmit clock frequency of 40 MHz, 24 bits
of RGB data and 4 bits of LCD timing and control data
(FPLINE, FPFRAME, DRDY, CNTL) are transmitted at a rate
of 280 Mbps per LVDS data channel. Using a 40 MHz clock,
the data throughput is 140 Megabytes per second. This trans-
mitter is intended to interface to any of the FPD Link receivers.
The chipset is an ideal means to solve EMI and cable size
problems associated with wide, high speed TTL interfaces.
