signal. Figure 22 illustrates the LOS Declaration and
Clearance behavior in response to the first loss of sig-
nal event and then afterwards to the restoration of the
signal.
3.6.2
for DS3 and STS-1 Applications
When the XRT73L00 is operating in the DS3 or STS-
1 Modes it declares and clears LOS based on either:
Analog LOS (ALOS) Declaration/Clearance Criteria
or,
Digital LOS (DLOS) Declaration/Clearance Criteria
The LOS Declaration/Clearance Criteria
In the DS3 or STS-1 Modes the LOS output (RLOS)
is simply the logical OR of the ALOS and DLOS
states.
1. The Analog LOS (ALOS) Declaration/Clear-
ance Criteria
The XRT73L00 declares an Analog LOS (ALOS)
Condition if the amplitude of the incoming line signal
drops below a specific amplitude as defined by the
state of the LOSTHR input pin.
