Detailed Description
The SY88063AL is a high-sensitivity limiting post
amplifier that operates from a single +3.3V power supply
over
temperatures
from
–40°C
to
+85°C.
The
SY88063AL can process input signals up to 12.5Gbps
and as small as 20mVpp. It can also process signals as
small as 10mVpp with data rates as high as 10.7Gbps.
Figure 1 shows the acceptable input ranges. The
SY88063AL generates a LOS output signal that can be
fed back to /EN for output stability in the absence of a
signal at the input. LOSLVL sets the sensitivity of the
input amplitude detection. By adjusting the voltage at the
LOSLVL pin, either through an external voltage source
or a resistor, the SY88063AL can trigger LOS on signals
from 10mVpp to 70mVpp.
Input Amplifier/Buffer
Figure 2 shows a simplified schematic of the input stage.
The high-sensitivity of the input amplifier allows signals
as small as 10mVpp to be detected and amplified. The
input amplifier allows input signals as large as
1800mVpp. Input signals are amplified with a typically
38dB differential voltage gain. Since it is a limiting
amplifier, the SY88063AL outputs typically 700mVpp
voltage-limited waveforms for input signals that are
greater than 7mVpp.
Output Buffer
The SY88063AL’s CML output buffer is designed to
drive 50 lines and is internally terminated with 50 to
VCC. Figure 3 shows a schematic of the output stage.
Loss-of-Signal (LOS)
The SY88063AL generates a chatter-free loss-of-signal
(LOS) open-collector TTL output as shown in Figure 4.
LOS is used to determine if the input amplitude is too
small to be considered as a valid input. LOS asserts high
if the input amplitude falls below the threshold set by
LOSLVL and de-asserts low otherwise. LOS can be fed
back to the enable (/EN) input to maintain output stability
under a loss of signal condition. /EN de-asserts low the
true output signal without removing the input signals.
Typically, 3dB LOS hysteresis is provided to prevent
chattering.
LOS-Level Set
A programmable LOS level set pin (LOSLVL) sets the
threshold of the input amplitude detection. Connecting
an external resistor between VCC and LOSLVL sets the
voltage at LOSLVL. This voltage ranges from VCC to
VCC-1.3V. The external resistor creates a voltage
divider between VCC and VCC-1.3V, as shown in Figure
5.
Hysteresis
The SY88063AL provides typically 3dB LOS electrical
hysteresis, which is defined as 20log (VINLOS-Assert /
VINLOS-De-Assert). Since the relationship between
the voltage out of the ROSA to optical power at its
input is linear, the optical hysteresis will be typically
half of the electrical hysteresis reported in the
datasheet, but in practice the ratio between electrical
and optical hysteresis is found to be within the range
1.5-1.8.
Digital Offset Correction
The SY88063AL features automatic digital offset
correction function. The conventional analog offset
correction is susceptible to offset drift from long input
patterns of exclusively 0s or 1s. The SY88063AL is not
limited by the input patterns. This feature will
automatically detect any existing offset and lock the
offset correction. The offset correction will not be
applied to large input signals that place the outputs
into limiting mode.
