DESCRIPTION

The DS90C365A is a pin to pin compatible

replacement for DS90C363, DS90C363A and

DS90C365. The DS90C365A has additional features

and improvements making it an ideal replacement for

DS90C363, DS90C363A and DS90C365. family of

LVDS Transmitters.

The DS90C365A transmitter converts 21 bits of

LVCMOS/LVTTL data into four LVDS (Low Voltage

Differential Signaling) data streams. A phase-locked

transmit clock is transmitted in parallel with the data

streams over the fourth LVDS link. Every cycle of the

transmit clock 21 bits RGB of input data are sampled

and transmitted. At a transmit clock frequency of 87.5

MHz, 21 bits of RGB data and 3 bits of LCD timing

and control data (FPLINE, FPFRAME, DRDY) are

transmitted at a rate of 612.5 Mbps per LVDS data

channel. Using a 87.5 MHz clock, the data throughput

is 229.687 Mbytes/sec. This transmitter can be

programmed for Rising edge strobe or Falling edge

strobe through a dedicated pin. A Rising edge or

Falling edge strobe transmitter will interoperate with a

Falling edge strobe FPDLink Receiver without any

translation logic.

This chipset is an ideal means to solve EMI and

cable size problems associated with wide, high-speed TTL interfaces with added Spead Spectrum Clocking

support..
