DESCRIPTION

The DS90C363 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 DS90CF364 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 throughput is 170 Mbyte/sec.

The Transmitter is offered with programmable edge

data strobes for convenient interface with a variety of

graphics controllers. The Transmitter can be

programmed for Rising edge strobe or Falling edge

strobe through a dedicated pin. A Rising edge

Transmitter will inter-operate with a Falling edge

Receiver (DS90CF364) without any translation logic.

This chipset is an ideal means to solve EMI and

cable size problems associated with wide, high speed

TTL interfaces.
