Data Input
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.
