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.

FEATUREs
■ Low equivalent input noise, typically 12 nA (RMS)
■ Wide dynamic range, typically 0.18 µA to 1.5 mA (p-p)
■ Differential transimpedance of 69 kΩ (typical)
■ Bandwidth from DC to 160 MHz (typical)
■ Differential outputs
■ On-chip (AGC) with possibility of external control
■ Single supply voltage 3.3 V; range 2.9 V to 3.6 V
■ Bias voltage for PIN diode
■ On-chip current mirror of average photo current for RSSI monitoring
■ Identical ports available on both sides of die for easy bond layout and RF polarity selection

APPLICATIONs
■ Digital fiber optic receiver modules in telecommunications transmission systems, in high speed data networks or in FTTx systems.
