General Description
The SY88313BL 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 SY88313BL quantizes these signals and
outputs CML-level waveforms.
The SY88313BL operates from a single +3.3V ±10%
supply, over temperatures ranging from –40°C to +85°C.
With its wide bandwidth and high gain, signals with data
rates up to 3.2Gbps, and as small as 10mVPP, can be
amplified to drive devices with CML inputs or AC-
coupled CML/PECL inputs.
The SY88313BL generates a loss-of-signal (LOS) open-
collector TTL output. 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, 3.4dB LOS hysteresis is provided to
prevent chattering.
