MAXIM MAX3738 155Mbps to 2.7Gbps SFF/SFP Laser Driver with Extinction Ratio Control handbook
The MAX3738 is a +3.3 V laser driver designed for multirate SFF/SFP transceiver modules covering data rates from 155 Mbps to 2.7 Gbps. It provides automatic power control, modulation compensation, and extinction‑ratio control, and complies with SFF‑8472 and SFP MSA timing requirements. Typical applications include multirate OC‑3 to OC‑48 transceivers, Gigabit Ethernet, and Fibre Channel modules.
Key features include a wide modulation current range (5 mA‑85 mA), bias‑current range up to 100 mA, TX_DISABLE and TX_FAULT pins for safety, and an exposed‑pad thin‑QFN package. The datasheet supplies absolute maximum ratings, electrical characteristics, pin descriptions, typical operating curves, layout recommendations, and package information.
