MAX3740ETG

The MAX3740ETG is one member of the MAX3740 family which is designed as the 3.2Gbps SFP VCSEL driver with diagnostic monitor that can be used in (1)multirate (1Gbps to 3.2Gbps) SFP/SFF modules; (2)gigabit ethernet optical transmitters; (3)fibre channel optical transmitters; (4)infiniband optical transmitters. This device safety circuit detects faults that could cause hazardous light levels and disables the VCSEL output and is available in a compact 4mm x 4mm, 24-pin thin QFN package and operates over the -40°C to +85°C temperature range.

Features of the MAX3740ETG are:(1)Supports all SFF-8472 Digital Diagnostics; (2)2mA to 15mA Modulation Current; (3)1mA to 15mA Bias Current; (4)Optional Peaking Current to Improve VCSEL Edge Speed; (5)Supports Common Cathode and Differential Configuration; (6)Automatic Power Control; (7)Safety Circuits Compliant with SFF and SFP MSAs; (8)4mm x 4mm 24-Pin Thin QFN Package.

The absolute maximum ratings of the MAX3740ETG can be summarized as:(1)Lead Temperature (soldering, 10s): +300°C;(2)Storage Temperature Range: -55°C to +150°C;(3)Operating Temperature Range: -40°C to +85°C;(4)Continuous Power Dissipation (TA = +85°C) 24-Lead Thin QFN (derate 20.8mW/°C above +85°C): 1354 mW;(5)Current into OUT+, OUT-: 60 mA;(6)Current into FAULT: -1mA to +25mA;(7)Voltage at OUT+, OUT-: (VCC - 2V) to (VCC + 2V).
