FEATURES
DESCRIPTION
The DS90CR217 transmitter converts 21 bits of
2
20 to 85 MHz Shift Clock Support
CMOS/TTL data into three LVDS (Low Voltage
50% Duty Cycle on Receiver Output Clock
Differential Signaling) data streams. A phase-locked
Best-in-Class Set & Hold Times on TxINPUTs
transmit clock is transmitted in parallel with the data
streams over a fourth LVDS link. Every cycle of the
Low Power Consumption
transmit clock 21 bits of input data are sampled and
±1V Common-Mode Range (Around +1.2V)
transmitted. At a transmit clock frequency of 85 MHz,
Narrow Bus Reduces Cable Size and Cost
21 bits of TTL data are transmitted at a rate of 595
Mbps per LVDS data channel. Using a 85 MHz clock,
Up to 1.785 Gbps Throughput
the data throughput is 1.785 Gbit/s (223 Mbytes/sec).
