General Description
The SY88782L is a single supply 3.3V low power
consumption,
telecom/datacom applications using FP/DFB lasers
at data rates up to 1.25Gbps. The driver can deliver
modulation current up to 90mA, and the high
compliance voltage it offers makes the part suitable
for high-current operation (with the laser AC- or DC-
coupled to it.) This device is intended to be used
with
Management IC which allows for modulation and
bias currents control and monitoring, automatic
power Control, and temperature compensation.
