DESCRIPTION
APPLICATIONS
GENERAL DESCRIPTION
The TZA3031AHL, TZA3031BHL and TZA3031U are fully
integrated laser drivers for STM1/OC3 (155 Mbits/s)
systems, incorporating the RF path between the data
multiplexer and the laser diode. Since the dual loop bias
and modulation control circuits are integrated on the IC,
the external component count is low. Only decoupling
capacitors and adjustment resistors are required.
The TZA3031AHL features an alarm function for signalling
extreme bias current conditions. The alarm low and high
threshold levels can be adjusted to suit the application
using only a resistor or a current Digital-to-Analog
Converter (DAC).
The TZA3031BHL is provided with an additional RF data
input to allow remote system testing (loop mode).
The TZA3031U is a bare die version for use in compact
laser module designs. The die contains 40 pads and
features the combined functionality of the TZA3031AHL
and the TZA3031BHL.
