Description

The TZA3011B is a fully integrated laser driver for optical transmission systems with data rates up to 3.2 Gbits/s.The TZA3011 incorporates all the necessary control and protection functions for a laser driver application with veryfew external components required and low power dissipation. The dual-loop controls the average monitor current in a programmable range from 150 mA to 1300 mA 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 TZA3011B package or as bare die. TheTZA3011A 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 and 5 V laser supply voltages.
