General Description Features The DS90C383 transmitter converts 28 bits of CMOS/TTL
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 link. Every cycle
of the transmit clock 28 bits of input data are sampled and
transmitted. The DS90CF384 receiver converts the LVDS
data streams back into 28 bits of CMOS/TTL data. At a transmit clock frequency of 65 MHz, 24 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 throughputs is 227
Mbytes/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 (DS90CF384) without any translation
logic. The DS90CF384 is also offered in 64 ball, 0.8mm fine
pitch ball grid array(FBGA) package which provides a 44 %
reduction in PCB footprint (available Q3, 1999). …
