Product Overview
The MAX3643ETG+T is a 155Mbps to 2.5Gbps burst mode laser driver in 24 pin TQFN package. This burst mode laser driver provides bias and modulation current drive for PON burst-mode ONT applications. It is specifically designed for use with a low cost external controller for APC (and if desired, AMC) loop. A high speed differential burst-enable input enables driver to switch laser from a dark (output off) condition to full on-condition in less than 2ns. When BEN is inactive, typical modulation and bias currents are 5µA each. Laser modulation current can be set from 10mA to 85mA and bias current can be set from 1mA to 70mA using MODSET and BIASSET inputs. A sample and hold circuit is provided to capture monitor diode output during short PON bursts, if needed and BEN high speed signal is mirrored on an LVCMOS output to be used by controller operating the APC/AMC loop. It is used in A/B/G/XGPON ONT modules up to 2.5Gbps and 1.25Gbps IEEE EPON ONT modules.
