3.0V to 5.5V, 2.5Gbps VCSEL

and Laser Driver

General Description

Features

The MAX3996 is a high-speed laser driver for small-

form-factor (SFF) fiber optic LAN transmitters. It con-

tains a bias generator, a laser modulator, and

comprehensive safety features. Automatic power con-

trol (APC) adjusts the laser bias current to maintain

average optical power, regardless of changes in tem-

perature or laser properties. The driver accommodates

common anode or differential laser configurations. The

output current range of the MAX3996 is appropriate for

VCSELs and high-efficiency edge-emitting lasers.

ꢀ Temperature Compensation of Modulation

The MAX3996 operates up to 3.2Gbps. It can switch up

to 30mA of laser modulation current and sink up to

60mA bias current. Adjustable temperature compensa-

tion is provided to keep the optical extinction ratio with-

in specifications over the operating temperature range.

The MAX3996 accommodates various laser packages,

including low-cost TO-46 headers. Low deterministic jit-

Ordering Information

This laser driver provides extensive safety features to

guarantee single-point fault tolerance. Safety features

include a transmit disable, redundant shutdown, and

laser-bias monitoring. The safety circuit detects faults

that could cause hazardous light levels and immediate-

ly disables the laser output. The MAX3996 safety cir-

cuits are compliant with SFF and small-form-factor

pluggable (SFP) multisource agreements (MSA).
