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.
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-
portion to the bias current. These control loops combined
with thermal compensation maintain a constant optical
extinction ratio over temperature and lifetime.
The MAX3737 accepts differential data input signals.
The wide 5mA to 60mA (up to 85mA AC-coupled) mod-
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
extended temperature range.
