ORDERING INFORMATION TYPE NUMBER TZA3001AHL TZA3001BHL TZA3001U - bare die; 2000 × 2000 × 380 µm TZA3001AHL; TZA3001BHL; TZA3001U APPLICATIONS - SDH/SONET STM4/OC12 optical transmission systems - SDH/SONET STM4/OC12 optical laser modules. GENERAL DESCRIPTION The TZA3001AHL, TZA3001BHL and TZA3001U are fully integrated laser drivers for STM4/OC12 (622 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 ponent count is low. Only decoupling capacitors and adjustment resistors are required. The TZA3001AHL 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 TZA3001BHL is provided with an additional RF data input to facilitate remote (loop mode) system testing. The TZA3001U is a bare die version for use in pact laser module designs. The die contains 40 pads and features the bined...
