FUNCTIONAL DESCRIPTION
The TZA3013 is a transimpedance amplifier intended for
use in fibre optic links for signal recovery in STM16/OC48
applications. It amplifies the current generated by a photo
detector (PIN diode or avalanche photodiode) and
converts it to a differential output voltage.
The most important characteristics of the TZA3013 are
high receiver sensitivity and wide dynamic range. High
receiver sensitivity is achieved by minimizing
transimpedance amplifier noise.
The TZA3013 has a wide dynamic range to handle the
signal current generated by the PIN diode which can vary
from 6
μ
A to 1.7 mA (p-p). This is implemented by an AGC
loop which reduces the preamplifier feedback resistance
so that the amplifier remains linear over the whole input
range. The AGC loop hold capacitor is integrated on-chip,
so an external capacitor is not required.
A differential amplifier converts the output of the
preamplifiertoadifferentialvoltage.Thedataoutputcircuit
is shown in Fig.3.
The logic level symbol definitions are shown in Fig.4.
