Information as of 2000-08-20
TZA3031AHL; TZA3031BHL; TZA3031U; SDH/SONET STM1/OC3 laser drivers
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.
