Multirate Laser Driver with Extinction
Ratio Control
General Description
The MAX3737 is a 3.3V laser driver designed for
multirate transceiver modules with data rates from
155Mbps to 2.7Gbps. Lasers can be DC-coupled to the
MAX3737 for reduced component count and ease of
multirate operation.

Features
Laser extinction ratio control (ERC) combines the features
of automatic power control (APC), modulation compensa-
tion, and built-in thermal compensation. The APC loop
maintains constant average optical power. Modulation
compensation increases the modulation current in pro-

with thermal compensation maintain a constant optical
extinction ratio over temperature and lifetime.
The MAX3737 accepts differential data input signals.

Ordering Information
ulation current range and up to 100mA bias current
range makes the MAX3737 ideal for driving FP/DFB
lasers in fiber-optic modules. External resistors set the
required laser current levels. The MAX3737 provides
transmit disable control (TX_DISABLE), single-point

fault tolerance, bias-current monitoring, modulation-cur-
rent monitoring, and photocurrent monitoring. The
device also offers a latched failure output (TX_FAULT)
to indicate faults, such as when the APC loop is no
longer able to maintain the average optical power at the
required level. The MAX3737 is compliant with the SFF-
8472 transmitter diagnostic and SFP MSA timing
requirements.
The MAX3737 is offered in a 5mm x 5mm 32-pin thin QFN
and QFN package and operates over the -40°C to +85°C
