SY88236L/AL Laser Driver

Micrel, Inc. and Digi-Key introduce 2.5Gbps burst mode laser driver

Micrel, Inc.'s 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 50Ω 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.
