General Description
The TIA56A is a versatile high-speed trans-
impedance amplifier designed for the
amplification and manipulation of signals with
data rates to over 43Gb/s with >28GHz
bandwidth. The TIA56A consists of a fully
symmetrical differential input and output buffer
and is optimized for 50 Ω line termination.

Output Characteristic
For applications which require adjustable input
bias or compensation of DC input currents (e.g.
photodiodes) the TIA56A allows adjusting the
bias input current for each input independently.
By using the output sensing pins, an offset
cancellation loop can be established.
The output voltage swing can be set up to to 800
mVpp differential by using the SWING option.
The symmetry of the output signal can be
optimized using the SYM option. This feature
can be used e.g. for optimizing the BER. The
input signal swing can be monitored using the
peak level detector (PLD) output.
