155Mbps to 3.2Gbps, Low-Power SFP

Limiting Amplifiers

General Description

Features

The MAX3747/MAX3747A 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 MAX3747 output voltage level is 500mVp-p

and the MAX3747A output voltage is 800mVp-p.

♦ Pin Compatible with Micrel SY88993V

♦ 155Mbps to 3.2Gbps Operation

♦ >57dB of Gain for the MAX3747 and MAX3747A

♦ <10

BER with 2mV

Input Amplitude

P-P

♦ 18mA Supply Current

♦ Chatter-Free LOS with Programmable Threshold

♦ Output DISABLE Function

The MAX3747/MAX3747A limiting amplifiers feature a

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

optional disable function (DISABLE). Output disable can

be used to implement squelch.

♦ PECL-Compatible Inputs

Ordering Information

The MAX3747/MAX3747A are available in a 3mm, 10-pin

µMAX® package ideal for small form-factor receivers.
