TZA3046
description
The TZA3046 is a transimpedance amplifier with Automatic Gain Control (AGC), designed to be used in Fiber Channel/Gigabit Ethernet (FC/GE) 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 pliant modules. The low noise characteristics makes it suitable for FC/GE applications, but also for FTTx applications.
CAUTION This device is sensitive to Electro Static Discharge (ESD). Therefore care should be taken during transport and handling.
