General Description
The SY88343DL low-power, high-sensitivity, 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 SY88343DL quantizes these
signals and outputs CML level waveforms.
The SY88343DL operates from a single +3.3V power
supply, over temperatures ranging from –40
oC to +85oC.
With its wide bandwidth, high gain, and 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 SY88343DL generates a high-gain loss-of-signal
(LOS) open-collector TTL output. This function has a
high-gain input stage for increased LOS 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.
