DESCRIPTION
APPLICATIONS
GENERAL DESCRIPTION
The TZA3041AHL, TZA3041BHL and TZA3041U are fully
integrated laser drivers for Gigabit Ethernet/Fibre Channel
(1.2 Gbits/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 TZA3041AHL 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 TZA3041BHL is provided with an additional RF data
input to facilitate remote (loop mode) system testing.
The TZA3041U is a bare die version for use in compact
laser module designs. The die contains 40 pads and
features the combined functionality of the TZA3041AHL
and the TZA3041BHL.
