Product data sheet
1. General description
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 compliant modules.
The low noise characteristics makes it suitable for STM1/OC3 applications, but also for
FTTx applications.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
