NSC FLINK5V6BT-65, DS90CF563MTDX, DS90CF563MTD Datasheet

DS90CF563/DS90CF564 LVDS 18-Bit Color Flat Panel Display (FPD) Link— 65 MHz
General Description
The DS90CF563 transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phase-lockedtransmit clock is transmitted in parallel with the data streams over a fourth LVDSlink. Every cycle of the transmit clock 21 bits of input data are sampled and transmitted. The DS90CF564 receiver converts the LVDS data streams back into 21 bits of CMOS/TTL data. At a transmit clock frequency of 65 MHz, 18 bits of RGB data and 3 bits of LCD timing and control data (FPLINE, FPFRAME, DRDY) are transmitted ata rate of 455 Mbps per LVDSdata channel. Usinga 65 MHz clock, thedata through­put is 171 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.
