MAX3711

125Mbps to 3.125Gbps Integrated Limiting Amplifier/

Laser Driver with Dual-Loop Power Control

General Description

Benefits and Features

The MAX3711 limiting amplifier and laser driver provides

a highly integrated, low-cost, high-performance PMD

solution.

S Simplifies Module Manufacturing

 Enables Single-Temperature Module Testing

 Production Laser Auto-Calibration Mode

The low-jitter laser diode driver provides transmit aver-

age power control (APC) of laser bias current as well as

an integrated modulation current control loop (extinction

ratio control, or ERC). The ERC eliminates the need for

temperature lookup tables (LUTs) controlling the modula-

tion current.

S Improved Performance

 Integrated APC Loop (Operates Up to

3.125Gbps)

 Integrated ERC Loop (Operates Up to 2.7Gbps)

 1.3mV

Receiver Sensitivity

P-P

S Flexibility

The low-noise limiting amplifier maximizes optical sen-

sitivity and has adjustable SD/LOS threshold plus pro-

grammable output levels. The differential CML output

stage features a slew-rate adjustment for 1.25Gbps

operation. Integrated bias current monitor and Tx power

monitor enable a low-cost implementation of modules

with digital diagnostics.

 LVDS, LVPECL, and CML Compatible High-

Speed I/Os

 Programmable I/O Polarity

 3-Wire Digital Interface

S Safety and Reliability

 Integrated Safety Features with FAULT Mask

A novel auto-calibration mode enables low-cost fiber

optic module production. An integrated 3-wire digital

interface controls the laser driver and limiting amplifier

functions, and enables communication with a low-cost

controller.

 Supports SFP MSA and SFF-8472 Digital

Diagnostic

 Selectable Analog Monitor of Laser Power or

BIAS Current at BMON Pin

Applications

The MAX3711 is offered in a small, 4mm x 4mm, 24-pin

TQFN package with exposed pad, and operates over the

-40NC to +95NC temperature range.

OC-3 to OC-48 SFP/SFF Transceivers

Ethernet SFP/SFF Transceivers

CPRI/OBSAI SFP/SFF Transceivers

CWDM SFP Transceivers
