SY88993V

Micrel

General

The SY88993V 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

SY88993V 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.
