GENERAL DESCRIPTION
The TZA3011 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 very
few external components required and low power
dissipation. The dual-loop controls the average monitor
current in a programmable range from 150
μ
A to 1300
μ
A
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 and 5 V laser supply
voltages.
