TZA3031BHL 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 i.

TZA3031BHL Features

* 155 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
