1Gbps to 4.25Gbps Multirate VCSEL  
Driver with Diagnostic Monitors  
General Description  
Features  
The MAX3795 is a high-speed VCSEL driver for small-  
form-factor (SFF) and small-form-factor pluggable (SFP)  
fiber optic transmitters. It contains a bias generator, a  
laser modulator, and comprehensive safety features.  
The automatic power control (APC) adjusts the laser  
bias current to maintain average optical power over  
changes in temperature and laser properties. The dri-  
ver accommodates common-cathode and differential  
configurations.  
♦ Supports All SFF-8472 Digital Diagnostics  
♦ 3.3V ±±10 Singlꢀ Supplꢁ  
♦ 2mA to ±5mA Modulation Currꢀnt  
♦ ±mA to ±5mA Bias Currꢀnt  
♦ 52ps Transition Timꢀ  
♦ 8.4ps Dꢀtꢀrministic Jittꢀr  
♦ Optional Pꢀaking Currꢀnt to Improvꢀ VCSEL Edgꢀ  
The MAX3795 operates up to 4.25Gbps. It can switch  
up to 15mA of laser modulation current and source up  
to 15mA of bias current. Adjustable temperature com-  
pensation is provided to keep the optical extinction  
ratio within specifications over the operating tempera-  
ture range. The MAX3795 interfaces with the Dallas  
DS1856/DS1859 to meet SFF-8472 timing and diagnos-  
tic requirements. The MAX3795 accommodates various  
VCSEL packages, including low-cost TO-46 headers.  
Spꢀꢀd  
♦ Supports Common-Cathodꢀ and Diffꢀrꢀntial  
Configuration  
♦ Safꢀtꢁ Circuits Compliant with SFF and SFP  
MSAs  
♦ Pin Compatiblꢀ to MAX3741A  
The MAX3795 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 (MSAs).  
Ordering Information  
PART  
TEMP RANGE PIN-PACKAGE  
The MAX3795 is available in a compact 4mm ✕ 4mm,  
24-pin thin QFN package and operates over the -40°C  
to +85°C temperature range. The MAX3795 is pin-for-  
pin compatible with the MAX3740A and is available in  
lead-free packages.
