DESCRIPTION
The SY88913V limiting post amplifier with its high gain
and wide bandwidth is ideal for use as a post amplifier in
fiber-optic receivers with data rates up to 1.5Gbps.
Signals as small as 5mVp-p can be amplified to drive
devices with PECL inputs. The SY88913V generates a
chatter-free PECL Loss of Signal (/LOS) output.
The SY88913V incorporates a programmble level
detect function to identify when the input signal has been
lost. This information can be fed back to the /EN input of
the device to maintain stability under loss of signal
conditions. Using LOSLVL pin the sensitivity of the level
detect can be adjusted. The LOSLVL voltage can be set
by connecting a resistor divider between VCC and VREF,
Figure 2. Figure 3 and 4 show the relationship between
input level sensitivity and the voltage set on LOSLVL.

GENERAL DESCRIPTION
General
The SY88913V is an integrated limiting amplifier intended
for high-frequency fiber-optic applications. The circuit
connects to typical transimpedance amplifiers found within
a fiber-optics link. The linear signal output from a
transimpedance amplifier can contain significant amounts
of noise, and may vary in amplitude over time. The
SY88913V limiting amplifier quantizes the signal and outputs
a voltage-limited waveform.
The TTL /EN pin allows the user to disable the signal
without removing the input signal.
