DS90CR481/DS90CR482,pdf datash

The DS90CR481 transmitter converts 48 bits of CMOS/TTL
data into eight LVDS (Low Voltage Differential Signaling)
data streams. A phase-locked transmit clock is transmitted in
parallel with the data streams over a ninth LVDS link. Every
cycle of the transmit clock 48 bits of input data are sampled
and transmitted. The DS90CR482 receiver converts the
LVDS data streams back into 48 bits of LVCMOS/TTL data.
At a transmit clock frequency of 112MHz, 48 bits of TTL data
are transmitted at a rate of 672Mbps per LVDS data channel.
Using a 112MHz clock, the data throughput is 5.38Gbit/s
(672Mbytes/s). At a transmit clock frequency of 112MHz, 48
bits of TTL data are transmitted at a rate of 672Mbps per
LVDS data channel. Using a 66MHz clock, the data throughput
is 3.168Gbit/s (396Mbytes/s).
