SY88232L_10 Datasheet, PDF (1/18 Pages) Micrel Semiconductor – 2.5Gbps Laser Diode Driver with Integrated

SY88232L/AL
2.5Gbps Laser Diode Driver with Integrated
Limiting Amplifier
General Description
The SY88232L is a single supply 3.3V integrated laser
driver and post amplifier for telecom/datacom applications
with data rates from 155Mbps up to 2.5Gbps. The driver
can deliver modulation current up to 85mA, and provides a
high compliance voltage that makes it suitable for high-
current operation with the laser DC-coupled to it. The post
amplifier can detect signals with amplitude as low as
5mV_PP.
The SY88232AL is a version of the SY88232L without 50Ω
termination resistors at the inputs of the driver and the post
amplifier. The SY88232AL is to be used specially in SFF
modules mounted on mother boards which have
preinstalled terminations. Removing post amplifier input
terminations will allow for receiver gain control.
