FEATURES
DESCRIPTION
The SY88933V 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 SY88933V
quantizes these signals and outputs PECL level waveforms.
The SY88933V operates from a single +3.3V or +5V
power supply, over temperatures ranging from –40
°
C to
+85
°
C. With its wide bandwidth and high gain, signals with
data rates up to 1.25Gbps and as small as 5mVp-p can be
amplified to drive devices with PECL inputs.
The SY88933V generates a TTL SD output. A
programmable signal-detect level set pin (SD
LVL
) sets the
sensitivity of the input amplitude detection. SD asserts high
if the input amplitude rises above the threshold set by SD
LVL
and deasserts low otherwise. EN deasserts the true output
signal without removing the input signal. Typically 4.6dB
SD hysteresis is provided to prevent chattering.
