General Description
The SY88343BL low-power limiting post amplifier is
designed for use in fiber-optic receivers. The device
connects to typical transimpedance amplifiers (TIAs)
that are AC-coupled. The linear signal output from TIAs
can contain significant amounts of noise and may vary
in amplitude over time. The SY88343BL quantizes these
signals and outputs CML-level waveforms.
The SY88343BL operates from a single +3.3V power
supply, over temperatures ranging from –40
oC to +85oC.
With its wide bandwidth and high gain, signals with data
rates up to 3.2Gbps and as small as 5mVPP can be
amplified to drive devices with CML inputs or AC-
coupled CML/PECL inputs.
The SY88343BL generates a high-gain loss-of-signal
(LOS) open-collector TTL output. The LOS function has
a high gain input stage for increased sensitivity. 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.
The enable bar input (/EN) de-asserts the true output
signal without removing the input signal. The LOS
output can be fed back to the /EN input to maintain
output
stability
under
a
loss-of-signal
condition.
Typically, 3.5dB LOS hysteresis is provided to prevent
chattering.
