General Description
The SY88053AL, limiting post amplifier is designed for
use in fiber-optic receivers for applications up to
12.5Gbps. It features a decision threshold control that
can be used for offset compensation or to optimize the
Bit Error Rate (BER) in noisy applications as WDM
where optical amplifiers such as EDFAs and Raman
amplifier are used. This device connects to typical
transimpedance amplifiers (TIAs). The signal from TIAs
can contain significant amounts of noise unevenly
distributed between its top and bottom rails due to the
Amplified Spontaneous Emission (ASE) noise generated
by the optical amplifiers. 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. An external voltage applied at the
VTHP pin on the SY88053AL will move the crossing
point up and down, from 20% to 80%, to achieve the
best BER.
The SY88053AL operates from a single +3.3V power
supply, over temperatures ranging from –40
and can detect and amplify signals up to 12.5Gbps and
amplitude as low as 15mV
The SY88053AL generates a Loss-of-Signal (LOS)
open-collector TTL output. A programmable Loss-of-
Signal level set pin (LOS
input amplitude detection. LOS asserts high if the input
amplitude falls below the threshold set by LOS
de-asserts low otherwise. The enable 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 implement the squelch function that maintains output
stability under a loss-of-signal condition.
