General Description
The SY88149CL 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 SY88149CL quantizes these signals and
outputs PECL level waveforms.
The SY88149CL 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 SY88149CL generates a high-gain signal-detect
(SD) open-collector TTL output. The SD function has a
high gain input stage for increased sensitivity. A
programmable Signal Detect level set pin (SDLVL) sets
the sensitivity of the input amplitude detection. SD
asserts high if the input amplitude rises above the
threshold set by SDLVL and de-asserts low otherwise.
The enable input (EN) de-asserts the true output signal
without removing the input signal. The SD output can be
fed back to the EN input to maintain output stability
under a loss-of-signal condition. Typically, 3.4dB SD
hysteresis is provided to prevent chattering.
