155Mbps to 2.5Gbps Burst-Mode  
Laser Driver  
General Description  
Features  
ꢀ Multirate Operation from 155Mbps to 2.5Gbps  
ꢀ Burst Enable/Disable Delay <2ns  
ꢀ Burst On-Time of 576ns to Infinity  
The MAX3656 is a burst-mode laser driver that oper-  
ates at data rates from 155Mbps up to 2.5Gbps. The  
laser driver accepts either positive-referenced emitter-  
coupled logic (PECL) or current-mode logic (CML) data  
inputs and provides bias and modulation current for the  
laser diode. The device can switch the laser diode from  
a completely dark (off) condition to a full (on) condition  
(with proper bias and modulation currents) in less than  
2ns. The MAX3656 incorporates DC-coupling between  
laser driver and laser diode and operates with a single-  
supply voltage as low as +3.0V.  
ꢀ Infinite Bias-Current Hold Time Between Bursts  
ꢀ DC-Coupled Operation with Single +3.3V Power  
Supply  
ꢀ 40mA Typical Supply Current  
ꢀ Programmable Bias Current from 1mA to 70mA  
ꢀ Programmable Modulation Current from 10mA  
to 85mA  
A digital automatic power-control (APC) loop is provided  
to maintain the average optical power over the full tem-  
perature range and lifetime. The APC loop is functional  
for a minimum burst on-time of 576ns and minimum  
burst off-time of 96ns, with no limit on the maximum  
burst on- or off-time. A fail monitor is provided to indi-  
cate when the APC loop can no longer maintain the  
average power. The MAX3656 can be configured for  
nonburst-mode applications (continuous mode) by con-  
necting burst enable (BEN) high. For power saving, the  
MAX3656 provides enabling and disabling functionality.  
The modulation current can be set from 10mA to 85mA  
and the bias current can be set from 1mA to 70mA.

The MAX3656 is packaged in a small, 24-pin, 4mm ✕  
4mm thin QFN package and consumes only 132mW  
(typ), excluding bias and modulation currents.
