Description
01F
[2]
REF2 frequency
> threshold
(read-only)
Readback register. Indicates if the frequency of the signal at REF2 is greater than the threshold frequency
set by Register 0x01A[6].
[2] = 0; REF2 frequency is less than the threshold frequency.
[2] = 1; REF2 frequency is greater than the threshold frequency.
01F
[1]
REF1 frequency
> threshold
(read-only)
Readback register. Indicates if the frequency of the signal at REF1 is greater than the threshold frequency
set by Register 0x01A[6].
[1] = 0; REF1 frequency is less than the threshold frequency.
[1] = 1; REF1 frequency is greater than the threshold frequency.
01F
[0]
Digital lock
detect
(read-only)
Readback register. Digital lock detect.
[0] = 0; PLL is not locked.
[0] = 1; PLL is locked.
