1. General 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 compliant modules.
The low noise characteristics makes it suitable for FC/GE applications, but also for
FTTx applications.
2. Features
n Low equivalent input noise current, typically 126 nA (RMS)
n Wide dynamic range, typically 2.5 µA to 1.7 mA (p-p)
n Differential transimpedance of 7.5 k (typical)
n Bandwidth from DC to 1050 MHz (typical)
n Differential outputs
n On-chip AGC with possibility of external control
n Single supply voltage 3.3 V, range 2.97 V to 3.6 V
n Bias voltage for PIN diode
n On-chip current mirror of average photo current for RSSI monitoring
n Identical ports available on both sides of die for easy bond layout and RF polarity
selection
3. Applications
n Digital fiber optic receiver modules in telecommunications transmission systems, in
high-speed data networks or in FTTx systems.
