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 SY88803V
quantizes these signals and outputs PECL level waveforms.

+85 C. With its wide bandwidth and high gain, signals with
data rates up to 155Mbps and as small as 5mVp-p can be
amplified to drive devices with PECL inputs.
