Value The Clock Source
Threshold parameter
indicates the lower quality
threshold of 2M external
clock source. When the clock
quality level of the external
clock source that is selected
from the 2M phase-locked
source priority table is
inferior to the threshold, the
2M phase-locked source
becomes invalid, and the
action specified for 2M
phase-locked source failure
is invoked to control the
external clock source output.
