MAX3741

19-2597; Rev 1; 5/04 3.2Gbps Compact SFP VCSEL Driver General Description The MAX3741 is a high-speed VCSEL driver for smallform-factor (SFF) and small-form-factor pluggable (SFP) fiber-optic LAN transmitters. It contains a bias generator, laser modulator, and peaking current option to improve VCSEL edge speed. The driver accommodates common cathode and differential configurations. The MAX3741 operates up to 3.2Gbps. It can switch up to 15mA of laser modulation current and source up to 15mA of bias current. The MAX3741 is designed to interface with a digital potentiometer and control circuitry. The MAX3741 accommodates various VCSEL packages, including low-cost TO-46 headers. The MAX3741 is available in a compact 3mm x 3mm 16-pin thin QFN package and operates over a temperature range of -40°C to +85°C. o 2mA to 15mA Modulation Current o 1mA to 15mA Bias Current o Optional Peaking Current to Improve VCSEL Edge Speed o Supports Common Cathode and Differential Configuration o 3mm × 3mm 16-Pin Thin QFN Package Features MAX3741 Applications Multirate (1Gbps to 3.2Gbps) SFP/SFF Modules Gigabit Ethernet Optical Transmitters Fibre Channel Optical Transmitters PART MAX3741ETE Ordering Information TEMP RANGE -40°C to +85°C PINPACKAGE 16 Thin QFN PKG.
