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.

FEATURES
■ Up to 1.25Gbps operation
■ 75mA peak drive current
■ Separate modulation control
■ Separate output enable for laser safety
■ Differential inputs for data
■ 75KΩ input pulldown resistor
■ Single power supply
■ Available in 16-pin SOIC package
