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 SY88793V
quantizes these signals and outputs PECL level waveforms.
power supply, over temperatures ranging from –40 C to
+85 C. With its wide bandwidth and high gain, signals with
data rates up to 622Mbps and as small as 5mVp-p can be
amplified to drive devices with PECL inputs.

sensitivity of the input amplitude detection. SD asserts high
if the input amplitude rises above the threshold set by SD
and deasserts low otherwise. EN deasserts the true output
signal without removing the input signal. Typically 6dB SD
hysteresis is provided to prevent chattering.
