Output Termination
The SY88923AV outputs must be terminated with a 50
load to V
CC – 2V (or Thevenin equivalent).
Layout and PCB Design
Since the SY88923AV is a high-frequency component,
performance can largely be determined by board layout
and design. A common problem with high-gain amplifiers is
feedback from the large swing outputs to the input via the
power supply.

DESIGN PROCEDURE
General
The SY88923AV is an integrated limiting amplifier
intended for high-frequency fiber-optic applications. The
circuit connects to typical trans-impedance amplifiers found
within a fiber-optics link. The linear signal output from a
trans-impedance amplifier can contain significant amounts
GENERAL DESCRIPTION
of noise, and may vary in amplitude over time. The
SY88923AV limiting amplifier quantizes the signal and
outputs a voltage-limited waveform.
The /EN pin allows the user to disable the output signal
without removing the input signal.
The SY88923AV ground pin should be connected to the
circuit board ground. Use multiple PCB vias close to the
part to connect to ground. Avoid long, inductive runs which
can degrade performance.
