3. Applications
CAUTION
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 compliant modules.
The low noise characteristics makes it suitable for FC/GE applications, but also for
FTTx applications.
