MAX3747A/MAX3747B

155Mbps to 3.2Gbps, Low-Power SFP

Limiting Amplifiers

General Description

Features

The MAX3747A/MAX3747B multirate limiting amplifiers

function as data quantizers for OC-3 through OC-48 syn-

chronous optical network (SONET), Fibre-Channel, and

Gigabit Ethernet optical receivers. They are pin-for-pin

compatible with the SY88993V from Micrel

Semiconductor, Inc. The amplifiers accept a wide range

of input voltages and provide constant-level, current-

mode logic (CML) output voltages with controlled edge

speeds. The MAX3747A/MAX3747B output voltages are

o Pin Compatible with Micrel SY88993V

o 155Mbps to 3.2Gbps Operation

o > 57dB of Gain

o < 10

BER with 2mV

Input Amplitude

P-P

o 18mA Supply Current

o Chatter-Free LOS with Programmable Threshold

o Output DISABLE Function

800mV . The MAX3747B has enhanced LOS operation

P-P

under overload conditions.

o PECL-Compatible Inputs

The MAX3747A/MAX3747B limiting amplifiers feature a

programmable loss-of-signal detect (LOS) and an

optional disable function (DISABLE) that can be com-

bined to implement squelch.

Ordering Information

The MAX3747A/MAX3747B are available in a 3mm, 10-

pin µMAX® package ideal for small form-

factor receivers.
