General Description

The DS90CR285 transmitter converts28 bitsof LVCMOS/
LVTTL data into four LVDS (Low Voltage Differential Signal-
ing) data streams.A phase-locked transmit clockis transmit-
tedin parallel with the data streams overa fifth LVDS link.
Every cycleof the transmit clock28 bitsof input data are
sampled and transmitted. The DS90CR286 receiver con-
vertsthe LVDS data streams back into28 bitsof LVCMOS/
LVTTL data.Ata transmit clock frequencyof66 MHz,28 bits TTL dataare transmittedata rateof 462 Mbps per LVDS
data channel. Usinga66 MHz clock,the data throughputis
1.848 Gbit/s (231 Mbytes/s).
The multiplexingof the data lines providesa substantial
cable reduction. Long distance parallel single-ended buses
typically requirea ground wire per active signal (and have
very limited noise rejection capability).Thus,fora 28-bitwide
data and one clock,upto58 conductors are required. With
the Channel Link chipsetas fewas11 conductors(4 data
pairs,1 clock pair anda minimumof one ground) are
needed. This providesa 80% reductionin required cable
width, which providesa system cost savings, reduces con-
nector physical size and cost, and reduces shielding require-
ments dueto the cables’ smaller form factor.
The28 LVCMOS/LVTTL inputs can supporta varietyof
signal combinations. For example, seven 4-bit nibblesor
three 9-bit (byte+ parity) and1 control.
