| General Description |
The SY88236L is a single supply 3.3V integrated burst
mode laser driver and post amplifier for A-PON, B-PON,
EPON, GE-PON, and G-PON 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
5mVPP.
The SY88236AL is a version of the SY88236L without 50O
termination resistors at the inputs of the driver and the post
amplifier. The SY88236AL is to be used specially in SFF
modules mounted on ONU mother boards which have
preinstalled terminations. Removing post amplifier input
terminations will allow for receiver gain control.
