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.
The device incorporates plementary open collector outputs with a capability of driving peak current of 75 m A.
The laser driver current is adjustable by selection of RSET....
