DESCRIPTION

The DS90CF363B 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. 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 throughput is 170 Mbytes/sec. The DS90CF363B is fixed as a

Falling edge strobe transmitter and will interoperate

with a Falling edge strobe Receiver (DS90CF366)

without any translation logic.

This chipset is an ideal means to solve EMI and

cable size problems associated with wide, high speed

TTL interfaces.
