TZA3001BHL Datasheet (NXP) - SDH/SONET STM4/OC12 laser drivers

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
