General Description
The SY88345BL high-sensitivity 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 SY88345BL quantizes these signals and
outputs CML-level waveforms.
The SY88345BL operates from a single +3.3V +10%
power supply, and over temperatures ranging from
–40
oC to +85oC. With its wide bandwidth, high gain, and
signals with data rates up to 3.2Gbps and as small as
5mVPP can be amplified to drive devices with CML inputs
or AC-coupled CML/PECL inputs.
The SY88345BL generates a signal-detect (SD) open-
collector TTL output. 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 sets 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 loss-of-signal condition.
Typically, 3.5dB SD hysteresis is provided to prevent
chattering.
