TZA3001BHL SDH/SONET STM4/OC12 laser drivers

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 component count .

TZA3001BHL Features

* 622 Mbits/s data input, both Current-Mode Logic (CML) and Positive Emitter Coupled Logic (PECL) compatible; maximum 800 mV (p-p)

* Adaptive laser output control with dual loop, stabilizing optical ONE and ZERO levels

* Optional external control of laser modulation and biasi
