DESCRIPTION
The STLVDS385 transmitter converts 28 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 a fifth LVDS
TSSOP56
link. Every cycle of the transmit clock 28 bits of
input data are sampled and transmitted. At a
transmit clock frequency of 85 MHz, 24 bits of
RGB data and 3 bits of LCD timing and control
data (FPLINE, FPFRAME, DRDY) are transmitted
at a rate of 595 Mbps per LVDS data channel.
Using a 85 MHz clock, the data throughput is
297.5 Mbytes/sec. The 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 inter
operate with a Falling edge strobe Receiver
without any translation logic.
