Low-Power, 622Mbps to 3.2Gbps

Limiting Amplifier

MAX3746

General Description

Features

The MAX3746 multirate limiting amplifier functions as a

data quantizer for SONET, Fibre-Channel, and Gigabit

Ethernet optical receivers. The amplifier accepts a wide

range of input voltages and provides selectable-level,

current-mode logic (CML) output voltages with con-

trolled edge speeds. A received-signal-strength indica-

tor (RSSI) is available when the MAX3746 is

DC-coupled to the MAX3744/MAX3724 SFP transim-

pedance amplifier (TIA). A receiver consisting of the

MAX3744/MAX3724 and the MAX3746 can provide up

to 19dB RSSI dynamic range. Additional features

include a programmable loss-of-signal (LOS) detect, an

optional disable function (DISABLE), and an

output-signal polarity reversal (OUTPOL). Output dis-

able can be used to implement squelch.

♦ SFP Reference Design Available

♦ Low 115mW Power Consumption

♦ 16-Pin QFN Package with 3mm x 3mm Footprint

♦ 70ps Rise and Fall Time

♦ Loss-of-Signal with Programmable Threshold

♦ RSSI Interface (with MAX3744/MAX3724 TIA)

♦ Output Disable

♦ Polarity Select

♦ 8.4ps_P-PDeterministic Jitter (3.2Gbps)

♦ Improved EMI Performance

The combination of the MAX3746 and the MAX3744/

MAX3724 allows for the implementation of all the small-

form-factor SFF-8472 digital diagnostic specifications

using a standard 4-pin TO-46 header.

♦ Selectable CML Output levels

♦ Pin Compatible with MAX3748A

Ordering Information

The MAX3746 is pin-for-pin compatible with the

MAX3748A limiting amplifier and consumes 30% less

power. The MAX3746 is packaged in a 3mm x 3mm,

16-pin QFN package.
