General Description
Eye Diagram
The TIA56 is a versatile high-speed trans-
impedance amplifier designed for the
amplification and manipulation of signals with
data rates to over 43Gb/s. The TIA56 consists
of a fully symmetrical differential input and output
buffer and is optimized for 50 Ω line termination.
For applications which require adjustable input
bias or compensation of DC input currents (e.g.
photodiodes) the TIA56 allows adjusting the bias
input current for each input independently. By
using the output sensing pins, an offset
cancellation loop can be established.
The TIA56 exhibits
a
fully symmetrical
Differential output signal at 43Gbps
differential output buffer which provides either
one differential output signal or two single ended
output signals. The output voltage swing is fixed
to 600 mVpp differential, or 300 mVpp single
ended.
