3.2Gbps SFP VCSEL Driver with Diagnostic  
Monitors  
General Description  
Features  
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.  
ꢀ Supports all SFF-8472 Digital Diagnostics  
ꢀ 2mA to 15mA Modulation Current  
ꢀ 1mA to 15mA Bias Current  
ꢀ Optional Peaking Current to Improve VCSEL Edge  
Speed  
ꢀ Supports Common Cathode and Differential  
Configuration  
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.  
ꢀ Automatic Power Control  
ꢀ Safety Circuits Compliant with SFF and SFP  
MSAs  
ꢀ 4mm ✕ 4mm 24-Pin Thin QFN Package  
Ordering Information  
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).
