The
User Controls
page allows the user to program bits not available on other pages. Of note is the
LD_MUX and HOLDOVER_MUX registers for controlling the status outputs. These allow the user to set
the status outputs to display PLL1 or PLL2 digital lock detect. Other common settings are PLLX R/2 or
PLLX N/2 to troubleshoot PLL locking issues. This displays half the frequency at the phase detector from
the R or N path. Unexpected frequencies from either of these nodes will help to determine if the lock issue
is associated with reference or feedback path.
