2 / 14 page DS90CR563/DS90CR564 LVDS 18-Bit Color Flat Panel Display (FPD) Link— 65 MHz General Description The DS90CR563 transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fourth LVDS link. Every cycle of the transmit clock 21 bits of input data are sampled and transmitted. The DS90CR564 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 at a rate of 455 Mbps per LVDS data channel. Using a 65 MHz clock, the data through- put is 171 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. Features n 20 to 65 MHz shift clk support n Up to 171 Mbytes/s bandwidth n Cable size is reduced to save cost n 290 mV swing LVDS devices for low EMI n Low power CMOS design (< 550 mW typ) n Power-down mode saves power (< 0.25 mW) n PLL requires no external components n Low profile 48-lead TSSOP package n Rising edge data strobe n Compatible with TIA/EIA-644 LVDS standard n Single pixel per clock XGA (1024 x 768) n Supports VGA, SVGA, XGA and higher n 1.3 Gbps throughput Block Diagrams TRI-STATE® is a registered trademark of National Semiconductor Corporation.
