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 i
TZA3031U 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
