DS90CR287/DS90CR288A

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

Link-85 MHZ

General Description

Features

n 20 to 85 MHZ shift clock support

n 50% duty cycle on receiver output clock

n Best–in–Class Set & Hold Times on TxINPUTs

n Low power consumption

The DS90CR287 transmitter converts 28 bits of CMOS/TTL

data into four LVDS (Low Voltage Differential Signaling) data

streams. A phase-locked transmit clock is transmitted in par-

allel 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 DS90CR288A receiver converts the four

LVDS data streams back into 28 bits of CMOS/TTL data. At

a transmit clock frequency of 85 MHZ, 28 bits of TTL data are

transmitted at a rate of 595 Mbps per LVDS data channel.

Using a 85 MHZ clock, the data throughput is 2.38 Gbit/s

(297.5 Mbytes/sec).

1V common mode range (around +1.2V)

n Narrow bus reduces cable size and cost

n Up to 2.38 Gbps throughput

n Up to 297.5 Megabytes/sec bandwidth

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

n PLL requires no external components

n Rising edge data strobe

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

problems associated with wide, high speed TTL interfaces.

n Compatible with TIA/EIA-644 LVDS standard

n Low profile 56-lead TSSOP package
