General

The SY88923 is an integrated limiting amplifier intended

for high-frequency fiber-optic applications. The circuit

connects to typical transimpedance amplifiers found within

a fiber-optics link. The linear signal output from a

transimpedance amplifier can contain significant amounts

of noise, and may vary in amplitude over time. The SY88923

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.
