General Description
The SY88147DL is a high-sensitivity limiting post
amplifier designed for use in fiber-optic receivers. These
devices connect 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 SY88147DL quantizes these signals and
outputs PECL level waveforms.
The SY88147DL 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 1.25Gbps, and as small as 5mVPP, can be
amplified to drive devices with PECL inputs.
The SY88147DL 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.
