General Description
The SY88289AL 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 SY88289AL quantizes these signals and
outputs CML-level waveforms.
The SY88289AL 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 10mV
amplified to drive devices with CML inputs or AC-
coupled CML/PECL inputs.
The SY88289AL generates a loss-of-signal (LOS) open-
collector TTL output. A programmable loss-of-signal
level-set pin (LOS
amplitude detection. LOS asserts high if the input
amplitude falls below the threshold set by LOS
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.
