SY100EL1003 Datasheet | Micrel Semiconductor

Micrel, Inc. LASER DIODE DRIVER WITH OUTPUT ENABLE Features s Up to 1.25Gbps operation s 75m A peak drive current s Separate modulation control s Separate output enable for laser safety s Differential inputs for data s 75KΩ input pulldown resistor s Single power supply s Available in 16-pin SOIC package DESCRIPTION The SY100EL1003 is a high speed current source for driving a semiconductor laser diode in optical transmission applications. The output current modulation is DC - voltage controlled. The modulation current is disabled when output enable is HIGH. The device incorporates plementary open collector outputs with a capability of driving peak current of 75m A. The laser driver current is adjustable by selection of RSET. The resistor REXT must be placed between OUT and VCC to dissipate the worst case power. RSER is remended to fix laser diode matching issues. The SY100EL1003 utilizes the high performance bipolar ASSET technology.
