Single +5V, Fully Integrated,  
1.25Gbps Laser Diode Driver  
_______________General Description  
____________________________Features  
Rise Times Less than 250ps  
The MAX3261 is a complete, easy-to-program, single  
+5V-powered, 1.25Gbps laser diode driver with com-  
plementary enable inputs and automatic power control  
(APC). The MAX3261 accepts differential PECL inputs  
and provides complementary output currents. A tem-  
perature-stabilized reference voltage is provided to  
simplify laser current programming. This allows modu-  
lation current to be programmed up to 30mA and bias  
current to be programmed up to 60mA with two exter-  
nal resistors.  
Differential PECL Inputs  
Single +5V Supply  
Automatic Power Control  
Temperature-Compensated Reference Voltage  
Complementary Enable Inputs  
Complementary enable inputs allow the MAX3261 to  
interface with open-fiber-control architecture—a feature  
not found in other 1.25Gbps laser diode drivers.

PIN-PACKAGE  
32 TQFP  
An APC circuit is provided to maintain constant laser power  
in transmitters that use a monitor photodiode. Only two  
external components are required to implement the APC  
function.

Dice*  
*Dice are designed to operate over a -40°C to +140°C junction  
temperature (Tj) range. Tested and guaranteed at Tj = +25°C.  
The MAX3261’s fully integrated feature set includes a  
TTL-compatible laser failure indicator and a program-  
mable slow-start circuit to prevent laser damage. The  
slow-start is preset to 50ns and can be extended by  
adding an external capacitor.
