LAN Laser Drivers
General Description
The MAX3286/MAX3296 series of products are high-
speed laser drivers for fiber optic LAN transmitters opti-
mized for Gigabit Ethernet applications. Each device
contains a bias generator, laser modulator, and com-
prehensive safety features. Automatic power control
(APC) adjusts the laser bias current to maintain aver-
age optical power at a constant level, regardless of
changes in temperature or laser properties. For lasers
without a monitor photodiode, these products offer a
constant-current mode. The circuit can be configured
for use with conventional shortwave (780nm to 850nm)
or longwave (1300nm) laser diodes, as well as vertical-
cavity surface-emitting lasers (VCSELs).
The MAX3286 series (MAX3286 –MAX3289) is opti-
mized for operation at 1.25Gbps, and the MAX3296

Ordering Information
series (MAX3296–MAX3299) is optimized for 2.5Gbps
operation. Each device can switch 30mA of laser mod-
ulation current at the specified data rate. Adjustable
temperature compensation is provided to keep the opti-
cal extinction ratio within specifications over the operat-
ing temperature range. This series of devices is
optimized to drive lasers packaged in low-cost TO-46
headers. Deterministic jitter (DJ) for the MAX3286 is
typically 22ps, allowing a 72% margin to Gigabit

These laser drivers provide extensive safety features to
guarantee single-point fault tolerance. Safety features
include dual enable inputs, dual shutdown circuits, and
a laser-power monitor. The safety circuit detects faults
that could cause dangerous light output levels. A pro-
grammable power-on reset pulse initializes the laser
driver at startup.
The MAX3286/MAX3296 are available in a compact, 5mm
? 5mm, 28-pin QFN or thin QFN package; a 5mm ? 5mm,
32-pin TQFP package; or in die form. The MAX3287/
MAX3288/MAX3289 and MAX3297/MAX3298/MAX3299
are available in a 16-pin TSSOP-EP package.
