transimpedance amplifier
TZA3023
FUNCTIONAL DESCRIPTION
The TZA3023 is a transimpedance amplifier intended for
use in fibre optic links for signal recovery in STM4/OC12
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 TZA3023 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
1
μ
A to 1.5 mA (p-p). An AGC loop is implemented to
make it possible to handle such a wide dynamic range.
TheAGCloopincreases thedynamic rangeofthe 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 13 on the bare die
(TZA3023U).Pad 13isnotbondedinthepackageddevice
(TZA3023T). This pad can be left unconnected during
normal operation. It can also be used to force an external
AGC voltage. If pad 13 is connected to GND, the internal
AGC loop is disabled and the receiver gain is at a
maximum. The maximum input current is then
approximately 50
μ
A.
A differential amplifier converts the single-ended output of
the preamplifier to a differential output voltage (see Fig.3).
