General Description

The SY88216L is a single supply 3.3V burst mode laser

driver 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.
