DESCRIPTION

The DS90CR218A receiver deserializes three input LVDS data streams into 21 bits of CMOS/TTL output

data. When operating at the maximum input clock

rate of 85 Mhz, the LVDS data is received at 595

Mbps per data channel for a total data throughput of

1.785 Gbit/sec (233 Mbytes/sec).

The narrow bus and LVDS signalling of the DS90CR218A is an ideal means to solve EMI and

cable size problems associated with wide, high-speed

TTL interfaces.
