The SY88983V low-power 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 SY88983V
quantizes these signals and outputs typically 800mVpp
voltage-limited waveforms.
The SY88983V operates from a single +3.3V
±10% or
+5V
±10% power supply, over the industrial temperature of
–40
°C to +85°C. With its wide bandwidth and high gain,
signals with data rates up to 3.2Gbps and as small as
10mVpp can be amplified to drive devices with CML inputs
or AC-coupled PECL inputs.
The SY88983V generates a signal detect (SD) open-
collector TTL output with internal 5k
pull-up resistor. A
programmable signal detect level set pin (SD
LVL) sets the
sensitivity of the input amplitude detection. SD asserts high
if the input amplitude rises above the threshold set by SD
LVL
and de-asserts low otherwise. SD can be fed back to the
enable (EN) input to maintain output stability under a loss-
of-signal condition. EN de-asserts the true output signal
without removing the input signal. Typically, 4.6dB SD
hysteresis is provided to prevent chattering.
