DS90CR288 +3.3V Rising Edge Data Strobe LVDS 28-Bit Channel Link Receiver - 75 MHz
May 2002
DS90CR288
+3.3V Rising Edge Data Strobe LVDS 28-Bit Channel
Link Receiver - 75 MHz
General Description
The DS90CR287 (see DS90CR287/288A datasheet) trans-
mitter converts 28 bits of CMOS/TTL data into four LVDS
(Low Voltage Differential Signaling) data streams. A phase-
locked transmit clock is transmitted in parallel with the data
streams over a fifth LVDS link. Every cycle of the transmit
clock 28 bits of input data are sampled and transmitted. The
DS90CR288 receiver converts the four LVDS data streams
back into 28 bits of CMOS/TTL data. At a transmit clock
frequency of 75 MHz, 28 bits of TTL data are transmitted at
a rate of 525 Mbps per LVDS data channel. Using a 75 MHz
clock, the data throughput is 2.10 Gbit/s (262.5 Mbytes/sec).
Complete specifications for the DS90CR287 are located in
the DS90CR287/DS90CR288A datasheet. The DS90CR287
supports clock rates from 20 to 85 MHz.
This chipset is an ideal means to solve EMI and cable size
problems associated with wide, high-speed TTL interfaces.
