TZA3011A; TZA3011B
30 Mbit/s up to 3.2 Gbit/s A-rate™ laser drivers
Rev. 06 — 20 January 2005
Product data sheet
1. General description
The TZA3011 is a fully integrated laser driver for optical transmission systems with data
rates up to 3.2 Gbit/s. The TZA3011 incorporates all the necessary control and protection
functions for a laser driver application with very few external components required and low
power dissipation. The dual-loop controls the average monitor current in a programmable
range from 150
µA
to 1300
µA
and the extinction ratio in a programmable range from
5 to 15 (linear scale).
The design is made in the Philips BiCMOS RF process and is available in a HBCC32
package or as bare die. The TZA3011A is intended for use in an application with an
AC-coupled laser diode with a 3.3 V laser supply voltage. The TZA3011B is intended for
use in an application with a DC-coupled laser diode for both 3.3 V and 5 V laser supply
voltages.
