MAX3643 Datasheet 155mbps To 2.5gbps Burst-mode Laser Driver

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: EVALUATION KIT AVAILABLE MAX3643 155Mbps to 2.5Gbps Burst-Mode Laser Driver.

General Description

The MAX3643 burst-mode laser driver provides bias and modulation current drive for PON burst-mode ONT applications.

It is specifically designed for use with a low-cost external controller for the APC (and if desired, AMC) loop.

A high-speed differential burst-enable input enables the driver to switch the laser from a dark (output off) condition to full on-condition in less than 2ns.

Key Features

  • 10mA to 85mA Modulation Current.
  • 1mA to 70mA Bias Current.
  • Monitor Diode Sample and Hold.
  • 45ps Output Transition Time.
  • 2ns Turn-On/-Off Time.
  • Reference Voltage Generator.
  • LVPECL High-Speed Inputs (Data, Burst Enable) Ordering Information PART TEMP RANGE PIN-.
