MAX3656 - 155Mbps to 2.5Gbps Burst-Mode Laser Driver

General Description

The MAX3656 is a burst-mode laser driver that operates at data rates from 155Mbps up to 2.5Gbps.

The laser driver accepts either positive-referenced emittercoupled logic (PECL) or current-mode logic (CML) data inputs and provides bias and modulation current for the laser diode.

Key Features

  • Multirate Operation from 155Mbps to 2.5Gbps Burst Enable/Disable Delay.

19-2790; Rev 1; 5/04 155Mbps to 2.5Gbps Burst-Mode Laser Driver General Description The MAX3656 is a burst-mode laser driver that operates at data rates from 155Mbps up to 2.5Gbps. The laser driver accepts either positive-referenced emittercoupled logic (PECL) or current-mode logic (CML) data inputs and provides bias and modulation current for the laser diode. The device can switch the laser diode from a completely dark (off) condition to a full (on) condition (with proper bias and modulation currents) in less than 2ns. The MAX3656 incorporates DC-coupling between laser driver and laser diode and operates with a singlesupply voltage as low as +3.0V. A digital automatic power-control (APC) loop is provided to maintain the average optical power over the full temperature range and lifetime.
