General

The SY88993AV 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

SY88993AV 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.
