3.0V to 5.5V, 2.5Gbps VCSEL
and Laser Driver
General Description
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.
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-
ter (9ps P-P ), combined with fast edge transitions,
(65ps) provides excellent margins compared to indus-

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).
The MAX3996 is available in a compact 4mm ? 4mm,
20-pin QFN package and a 20-pin thin QFN package. It
operates over a temperature range of 0°C to +70°C.
