General Description
The SY88973BL
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 SY88973BL
quantizes these signals and outputs typically 800mVPP
voltage-limited waveforms.
The SY88973BL operates from a single +3.3V ±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 SY88973BL incorporates a loss-of-signal (LOS), open-
collector TTL output with external 4.75k
to 10k pull-up
resistor to fully comply with SFP MSA. 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 sets 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.
