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.
