The SY88773V 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 SY88773V
quantizes these signals and outputs typically 800mVPP
voltage-limited waveforms.
The SY88773V operates from a single +3.3V
±10% or
+5V
±10% power supply, over an industrial temperature
range 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 SY88773V incorporates a loss-of-signal (LOS), open-
collector TTL output with internal 4.75k
pull-up resistor. A
programmable, loss-of-signal level set pin (LOSLVL) sets
the sensitivity of the input amplitude detection. LOS asserts
high if the input amplitude falls below the threshold set by
LOSLVL and de-asserts low otherwise. LOS 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 LOS hysteresis is provided to prevent chattering.
