The TZA3026 is a transimpedance ampliﬁer with Automatic Gain Control (AGC), designed to be used in STM4/OC12 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 SFF8472 compliant modules.

s s s s s s s s s s Low equivalent input noise current, typically 67 nA (RMS) Wide dynamic range, typically 0.85 µA to 1.5 mA (p-p) Differential transimpedance of 14 kΩ (typical) Bandwidth from DC to 650 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 Current output of average photo current for RSSI monitoring Identical ports available on both sides of die for easy bond layout and RF.
