SY88982L
3.3V, 2.7Gbps High-Current, Low-Power
Laser Driver for FP/DFB Lasers
General Description
Features
The SY88982L is a single 3.3V supply, low power
consumption, small form factor driver for
telecom/datacom applications using FP/DFB lasers
at data rates up to 2.7Gbps. The driver can deliver
modulation current up to 90mA, and the high
compliance voltage if 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 Micrel’s MIC3003 Optical Transceiver
Management IC, which allows for both modulation
and bias current control and monitoring, automatic
power control, and temperature compensation.
All support documentation can be found on Micrel’s
