www.ti.com SNLS047H – FEBRUARY 2000 – REVISED APRIL 2013 DS90CR483 / DS90CR484 48-Bit LVDS Channel Link SER/DES — 33 -112 MHz
Check for Samples: DS90CR483, DS90CR484 FEATURES DESCRIPTION The DS90CR483 transmitter converts 48 bits of
CMOS/TTL data into eight LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked
transmit clock is transmitted in parallel with the data
streams over a ninth LVDS link. Every cycle of the
transmit clock 48 bits of input data are sampled and
transmitted. The DS90CR484 receiver converts the
LVDS data streams back into 48 bits of CMOS/TTL
data. At a transmit clock frequency of 112MHz, 48
bits of TTL data are transmitted at a rate of 672Mbps
per LVDS data channel. Using a 112MHz clock, the
data throughput is 5.38Gbit/s (672Mbytes/s). 1 2 Up to 5.38 Gbits/sec Bandwidth
