General Description

The SY88933AL high-sensitivity limiting post amplifier is designed for use in fiber-optic receivers. The device connects to typical transimpedance amplifiers (TIAs). The linear signal output from TIAs can contain significant amounts of noise and may vary in amplitude over time. The SY88933AL quantizes these signals and outputs PECL level waveforms.
