MAX3643

The MAX3643 is designed as one kind of 155Mbps to 2.5Gbps burst-mode laser driver device that can be used in (1)A/B/G/XGPON ONT Modules Up to 2.5Gbps; (2)1.25Gbps IEEE EPON ONT Modules applications. And this device is packaged in a 4mm x 4mm, 24-pin thin QFN package. It operates from -40°C to +85°C.

Features of the MAX3643 are:(1)10mA to 85mA Modulation Current; (2)1mA to 70mA Bias Current; (3)Monitor Diode Sample and Hold; (4)45ps Output Transition Time; (5)2ns Turn-On/-Off Time; (6)Reference Voltage Generator; (7)LVPECL High-Speed Inputs (Data, Burst Enable).

The absolute maximum ratings of the MAX3643 can be summarized as:(1)Supply Voltage VCC: -0.5V to +4.0V;(2)Current into BIAS-, BIAS+, OUT-, OUT+: -20mA to +150mA;(3)Voltage at MODSET, BIASSET, VREF, IMAX: -0.5V to +3.0V;(4)Voltage at OUT-, OUT+, BIAS-, BIAS+: +0.3V to (VCC + 0.5V);(5)Operating Temperature Range: -40°C to +85°C;(6)Storage Temperature Range: -55°C to +150°C;(7)Lead Temperature (soldering, 10s): +300°C;(8)Soldering Temperature (reflow): +260°C or +240°C.
