General

The SY88913 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 SY88913

limiting amplifier quantizes the signal and outputs a voltage-

limited waveform.

The TTL /EN pin allows the user to disable the signal

without removing the input signal.
