General DescriptionThe DS90CR217 transmitter converts21 bitsof CMOS/TTL
data into three LVDS (Low Voltage Differential Signaling)
data streams. Aphase-locked transmit clockis transmittedin
parallel withthe data streams overa fourth LVDS link. Every
cycleofthe transmit clock21 bitsof input dataare sampled
and transmitted. The DS90CR218A receiver converts the
three LVDS data streams back into21 bitsof CMOS/TTL
data.Ata transmit clock frequencyof85 MHz,21 bitsof TTL
data are transmittedata rateof 595 Mbps per LVDS data
channel. Usinga85 MHz clock,the data throughputis 1.785
Gbit/s (223 Mbytes/sec).
This chipsetisan ideal meansto solve EMI and cable size
problems associated with wide, high-speed TTL interfaces.
