DS90C363B
+3.3V Programmable LVDS Transmitter 18-Bit Flat Panel
Display (FPD) Link -65 MHz
General Description
The DS90C363B 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 DS90C363B trans-
mitter 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 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.
