SY88923V
GENERAL DESCRIPTION
General
The SY88923V 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 of noise,
and may vary in amplitude over time. The SY88923V 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.

NOTE:
1. Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to ABSOLUTE MAXIMUM RATlNG conditions for extended
periods may affect device reliability.
