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 complementary open collector
outputs with a capability of driving peak current of 75mA.
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
recommended to fix laser diode matching issues.
The SY100EL1003 utilizes the high performance
bipolar ASSET technology.
