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.
