SY88232L/AL 2.5Gbps Laser Diode Driver with Integrated Limiting Amplifier General Description Features The SY88232L is a single supply 3.3V integrated laser 2.4V minimum laser compliance voltage driver and post amplifier for telecom/datacom applications Operation up to 2.5Gbps with data rates from 155Mbps up to 2.5Gbps. The driver Integrated APC circuit can deliver modulation current up to 85mA, and provides a Modulation current up to 85mA high compliance voltage that makes it suitable for high- current operation with the laser DC-coupled to it. The post Bias current up to 70mA amplifier can detect signals with amplitude as low as Bias, Modulation, and power monitoring 5mV . PP High input sensitivity post amplifier, 5mV PP The SY88232AL is a version of the SY88232L without 50 Programmable LOS level termination resistors at the inputs of the driver and the post Available in 32-pin (5mm x 5mm) QFN package amplifier. The SY88232AL is to be used specially in SFF modules mounted on mother boards which have Applications preinstalled terminations. Removing post amplifier input terminations will allow for receiver gain control. Multi-rate burst mode applications: A-PON, B-PON, G-PON, E-PON, GE-PON All support documentation can be found on Micrels web site at: www.micrel.com.
