SY88236AL

SY88236L/AL 2.5Gbps Burst Mode Laser Driver with Integrated Limiting Amplifier General Description Features ∑ 2.4V minimum laser compliance voltage The SY88236L is a single supply 3.3V integrated burst ∑ Operation up to 2.5Gbps mode laser driver and post amplifier for A-PON, B-PON, ∑ Fast burst mode enable/disable delay EPON, GE-PON, and G-PON applications with data rates ∑ Modulation current up to 85mA from 155Mbps up to 2.5Gbps. The driver can deliver modulation current up to 85mA, and provides a high ∑ Bias current up to 70mA compliance voltage that makes it suitable for high-current ∑ Infinite bias current hold time between bursts operation with the laser DC-coupled to it. The post ∑ Bias, Modulation, and power monitoring amplifier can detect signals with amplitude as low as ∑ High input sensitivity post amplifier, 5mVPP 5mVPP. ∑ Programmable LOS level The SY88236AL is a version of the SY88236L without 50Ω ® ∑ Available in 32-pin (5mm x 5mm) MLF package termination resistors at the inputs of the driver and the post amplifier. The SY88236AL is to be used specially in SFF Applications modules mounted on ONU mother boards which have preinstalled terminations. Removing post amplifier input ∑ Multi-rate burst mode applications: A-PON, B-PON, terminations will allow for receiver gain control. G-PON, E-PON, GE-PON All support documentation can be found on Micrel’s web site at: www.micrel.com. ____________________________________________________________________________________...
