Preliminary Data Sheet

SONET/SDH 2.5Gb/s Laser Diode Driver

VSC7927

Features

• Rise Times of Less Than 100ps

• Direct Access to Modulation and Bias FETs

• Data Density Monitors

• High Speed Operation

(Up to 2.5 Gb/s NRZ Data)

• On-Chip Reclocking Register

• Differential or Single-Ended Inputs

• Single Supply

• On-Chip Mux for Clocked or Non-clocked Appli-

General Description

The VSC7927 is a single 5V supply, 2.5 Gb/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 monitor-

ing and setting of the current levels. Data density outputs are provided to allow the user to adjust the laser bias

in high unbalanced data applications. Clock and data inputs are differentially terminated to 50Ω.

Applications

• SDH/SONET @ 622Mb/s, 1.244Gb/s, 2.488Gb/s

• Full Speed Fibre Channel (1.062Gb/s)
