MAX3738 - 155Mbps to 4.25Gbps SFF/SFP Laser Driver

General Description

The MAX3738 is a +3.3V laser driver designed for multirate transceiver modules with data rates from 155Mbps to 4.25Gbps.

Lasers can be DC-coupled to the MAX3738 for reduced component count and ease of multirate operation.

Key Features

  • of automatic power control (APC), modulation compensation, and built-in thermal compensation. The APC loop maintains constant average optical power. Modulation compensation increases the modulation current in proportion to the bias current. These control loops, combined with thermal compensation, maintain a constant optical extinction ratio over temperature and lifetime. The MAX3738 accepts differential data input signals. The wide 5mA to 60mA (up to 85mA AC-coupled) modulation current range and.

Lasers can be DC-coupled to the MAX3738 for reduced component count and ease of multirate operation. Laser extinction ratio control (ERC) combines the features of automatic power control (APC), modulation compensation, and built-in thermal compensation. The APC loop maintains constant average optical power. Modulation compensation increases the modulation current in proportion to the bias current.
