General Description
The MAX3740 is a high-speed VCSEL driver for small-
form-factor (SFF) and small-form-factor pluggable (SFP)
fiber optic LAN transmitters. It contains a bias genera-
tor, a laser modulator, and comprehensive safety fea-
tures. The automatic power control (APC) adjusts the
laser bias current to maintain average optical power
over changes in temperature and laser properties. The
driver accommodates common cathode and differential
configurations.
The MAX3740 operates up to 3.2Gbps. It can switch up
to 15mA of laser modulation current and source up to
15mA of bias current. Adjustable temperature compen-
sation is provided to keep the optical extinction ratio
within specifications over the operating temperature
range. The MAX3740 interfaces with the Dallas DS1858
to meet SFF-8472 timing and diagnostic requirements.
The MAX3740 accommodates various VCSEL pack-
ages, including low-cost TO-46 headers.
The MAX3740 safety circuit detects faults that could
cause hazardous light levels and disables the VCSEL
output. The safety circuits are compliant with SFF and
SFP multisource agreements (MSA).
The MAX3740 is available in a compact 4mm
4mm,
24-pin thin QFN package and operates over the -40°C
to +85°C temperature range.
