General Description
The SY88347DL 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 SY88347DL quantizes these signals and
outputs PECL-level waveforms.
The SY88347DL operates from a single +3.3V power
supply, over temperatures ranging from –40
With its wide bandwidth and high gain, signals with data
rates up to 3.2Gbps, and as small as 5mV
amplified to drive devices with PECL inputs.
The SY88347DL 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 (LOS
the sensitivity of the input amplitude detection. LOS
asserts high if the input amplitude falls below the
threshold sets by LOS
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
Typically, 3.3dB LOS hysteresis is provided to prevent
chattering.
