DS90CF583 Datasheet | National Semiconductor

Description The DS90CF583 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 DS90CF584 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 falling 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.
