TZA3036 - NXP

TZA3036 SDH/SONET STM1/OC3 transimpedance amplifier

The TZA3036 is a transimpedance amplifier with Automatic Gain Control (AGC), designed to be used in STM1/OC3 fiber optic links. It amplifies the current generated by a photo detector (PIN diode or avalanche photodiode) and converts it to a differential output voltage. It offers a current mirror of average photo current for RSSI monitoring to be used in SFF-8472.
