M02094

2 Gbps, 3.3 or 5V VCSEL/FP Laser Driver


Overview

Description

The M02094 is a highly integrated, programmable VCSEL driver intended for SFP/SFF modules to 2.0 Gbps. Using differential PECL data inputs, the M02094 supplies the bias and modulation current required to drive a VCSEL or edge-emitting laser. The modulation output can be AC or DC coupled to a FP laser diode or AC coupled to a common anode or common cathode VCSEL.

Features

  • High-speed operation; suitable for SFP/SFF applications from 155 Mbps to 2.0 Gbps
  • Typical rise/fall times < 110 ps
  • Supports common anode VCSEL, common cathode VCSEL, or FP Laser. May be used with or without a monitor photodiode.
  • Programmable temperature compensation. Modulation output and bias output can be controlled using a few discrete resistors.
  • Supports DDMI (SFF-8472) diagnostics
  • DC or AC coupled modulation drive
  • Peaking circuit to optimize VCSEL response
  • Low overshoot allows high extinction ratio with low jitter
  • Supports E-PON burst mode with no extra components
  • Automatic laser power control, with "Slow-Start"
  • 3.3 or 5 V operation
