TZA3036

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.

Features

• Low equivalent input noise, typically 12 nA (RMS)
• Wide dynamic range, typically 0.18 mA to 1.5 mA (p-p)
• Differential transimpedance of 69 kOhm (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
