OSN3500 2Mphase-lockedsourcefailure action" - when the reference signal of the external clock used for locking the output fails or falls below the threshold, the output action of the external clock should be controlled (cut off or insert AIS), this parameter is used to setthe failure action of the2M phase-lockedsource
2M phase-locked source failure conditions
Parameter meaning
"2M phase-locked source failure condition" - sets the failure condition of the 2M phase-locked source.
Impact on the system
Does not affect system operation.

Description |
|---|---|
|
No failure condition |
No failure condition is set. The 2M phase-locked source is not disabled when AIS or LOF is present in the external clock signal. |
|
AIS |
Set the failure condition to AIS. 2M phase-locked source is disabled when AIS appears on the external clock signal. |
|
LOF |
Set the failure condition to LOF. 2M phase-locked source fails when LOF appears on the external clock signal. |
|
AIS OR LOF |
Set the failure condition to AIS OR LOF. 2M phase-locked source fails when AIS or LOF appears on the external clock signal. |
Principle
The failure condition can be set arbitrarily according to the actual situation.
Relationship with other parameters
None
Reference information
None
The OSN3500can set its output action arbitrarily whenthe 2Mphase-lockedsourceis disabled, but when the "Output mode ofexternalsource" is2M Hz, the outputof the externalsource is always turned off regardless of the output action.
