FUNCTIONAL DESCRIPTION
The TZA3033 is a transimpedance amplifier intended for
use in fibre optic links for signal recovery in STM1/OC3
applications. It amplifies the current generated by a photo
detector (PIN diode or avalanche photodiode) and
transforms it into a differential output voltage. The most
important characteristics of the TZA3033 are high receiver
sensitivity and wide dynamic range.
High receiver sensitivity is achieved by minimizing noise in
the transimpedance amplifier.
The signal current generated by a PIN diode can vary
between 0.25
A to 1.6 mA (peak-to-peak value).
An AGC loop (see Fig.1) is implemented to make it
possible to handle such a wide dynamic range.
The AGC loop increases the dynamic range of the
receiver by reducing the feedback resistance of the
preamplifier. The AGC loop hold capacitor is integrated
on-chip, so an external capacitor is not needed for AGC.
The AGC voltage can be monitored at pad 15 on the naked
die (TZA3033U). Pad 15 is not bonded in the packaged
device (TZA3033T). This pad can be left unconnected
during normal operation. It can also be used to force an
external AGC voltage. If pad 15 (AGC) is connected to
VCC, the internal AGC loop is disabled and the receiver
gain is at a maximum. The maximum input current is then
about 10
A.
A differential amplifier converts the output of the
preamplifier to a differential voltage. The data output circuit
is given in Fig.4.
The logic level symbol definitions are shown in Fig.5.
