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 2.5 / 0 ns Set & Hold Times on TxINPUTs

n Low power consumption

The DS90CR287 transmitter converts 28 bits of LVCMOS/

LVTTL data into four LVDS (Low Voltage Differential Signal-

ing) data streams. A phase-locked transmit clock is transmit-

ted 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 DS90CR288A receiver con-

verts the four LVDS data streams back into 28 bits of

LVCMOS/LVTTL 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 Mbytes/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
