+3.3V Rising Edge Data Strobe LVDS 28-Bit Channel

Link Receiver - 75 MHz

General Description

Features

n 20 to 75 MHz shift clock support

n 50% duty cycle on receiver output clock

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).

n Best-in-Class Set & Hold Times on TxINPUTs and

RxOUTPUTs

n Low power consumption

n Tx + Rx Powerdown mode 400µW (max)

1V common-mode range (around +1.2V)

n Narrow bus reduces cable size and cost

n Up to 2.10 Gbps throughput

n Up to 262.5 Mbytes/sec bandwidth

n 345 mV (typ) swing LVDS devices for low EMI

n PLL requires no external components

n Rising edge data strobe

Complete specifications for the DS90CR287 are located in

the DS90CR287/DS90CR288A datasheet. The DS90CR287

supports clock rates from 20 to 85 MHz.

n Compatible with TIA/EIA-644 LVDS standard

n Low profile 56-lead TSSOP package

This chipset is an ideal means to solve EMI and cable size

problems associated with wide, high-speed TTL interfaces.
