The DS90CR215 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. The DS90CR216 receiver converts the
LVDS data streams back into 21 bits of CMOS/TTL data. At
a transmit clock frequency of 66 MHz, 21 bits of TTL data are
transmitted at a rate of 462 Mbps per LVDS data channel.
Using a 66 MHz clock, the data throughput is 1.386 Gbit/s
(173 Mbytes/s).
