VSC7928 - SONET/SDH 3.2Gb/s Laser Diode Driver

Datasheet Summary

Description

The VSC7928 is a single 5V supply, 3.2Gb/s laser diode driver with direct access to the laser modulation and bias FETs.

Laser bias and modulation currents are set by external components allowing precision monitoring and setting of the current levels.

Features

  • Rise Times Less Than 100ps.
  • High Speed Operation (Up to 3.2Gb/s NRZ Data).
  • Differential or Single-Ended Inputs.
  • Single Supply.
  • ECL Compatible Clock and Data Inputs.
  • Direct Access to Modulation and Bias FETs.
  • Data Density Monitors.
  • On-chip Reclocking Register.
  • On-chip Mux for Clocked or Non-clocked.
