General Description
The SY88353BL limiting post amplifier is designed for
use in fiber-optic receivers, and is specially optimized for
WDM applications where optical amplifiers such as
EDFAs and Raman amplifier are used. The device
connects to typical transimpedance amplifiers (TIAs).
The linear signal from TIAs can contain significant
amounts of noise that is unevenly distributed between
top and bottom rails due to the ASE noise generated by
the optical amplifiers, crosstalk, or non-linear effect in
the fiber. In order to optimize the BER in such noisy
conditions, the decision threshold between bit 1 and bit
0, needs to be moved to the rail that contains less noise.
The SY88353BL features a pin at which an external
voltage can be applied to move the crossing point up
and down, from 20% to 80%, for BER optimization
purposes.
The SY88353BL operates from a single +3.3V power
supply, over temperatures ranging from –40
oC to +85oC.
Signals with data rates from 155Mbps up to 3.2Gbps,
and as small as10mVpp, can be amplified to drive
devices with CML or PECL inputs.
The SY88353L features 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 sets 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, 3.3dB LOS hysteresis is provided to
prevent chattering.
