DESCRIPTION
The SY100EL1001 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 integrated circuit contains the following functional blocks:
    • Input Line Receiver
    • D Flip-Flop
    • Bias Control Circuitry
    • Output Current Switch

A logic HIGH level at the data input results in the modulation current flowing through the OUT pin on the next rising edge of the clock. A logic HIGH level at the master reset input will disable the modulation current.

FEATURES
■ Up to 1.25Gb/s operation
■ 75mA peak drive current
■ Separate modulation control
■ Separate master reset for laser safety
■ Differential inputs for data and clock
■ 75KΩ input pulldown resistor
■ Single power supply
■ Available in 16-pin SOIC package
