Quad 2.5Gbps Cable Transceiver

General Description

Features

The MAX3780 cable transceiver provides a bidirectional

interface of four 2.5Gbps channels over low-cost copper

cable or external fiber-optic interface. The transmitter

section accepts eight channels of input at 1.25Gbps. An

integrated 4-bit FIFO allows retiming of the transmit data

to a clean local reference clock. The channels are multi-

plexed (2:1) into four outputs operating at 2.5Gbps. Pre-

emphasis and equalization provide compensation for

losses in low-cost cables up to 3m. The receiver recov-

ers the clock and demultiplexes (1:2) the 2.5Gbps chan-

nels into eight 1.25Gbps outputs. Fully integrated

phase-locked loops and delay-locked loops recover

clock and data from the serial data inputs.

o Quad 2:1 Channel Serialization

o Quad 1:2 Channel Deserialization

o 3m Link Distance with Low-Cost Copper Cable

o Better than 10^-16BER Performance

o 10Gbps Aggregate Parallel Interface

o System Loopback

o 1.25Gbps LVDS Synchronous Interface

o 2.5Gbps CML Serial Cable Interface

o PLL Lock Detect Signal

The transceiver IC is available in a compact 100-pin

TQFP package with exposed-ground pad and con-

sumes 2.2W.

o Selectable Cable Pre-Emphasis

o Fixed Receive Equalization
