Description
018
[0]
VCO calibration
now
Bit used to initiate the VCO calibration. This bit must be toggled from 0 to 1 in the active registers. The
sequence to initiate a calibration follows: program to 0, followed by an IO_UPDATE bit (Register 0x232[0]);
then program to 1, followed by another IO_UPDATE bit (Register 0x232[0]). This sequence gives complete
control over when the VCO calibration occurs relative to the programming of other registers that can impact
the calibration (default = 0). Note that the VCO divider (Register 0x1E0[2:0]) must not be static during VCO
calibration.

Action
0
Do nothing on SYNC (default).

0
Synchronous reset.
1
Do nothing on SYNC.

[5:3]
R path delay
R path delay, see Table 2 (default: 0x0).
019
[2:0]
N path delay
N path delay, see Table 2 (default: 0x0).
01A
[7]
Enable STATUS
pin divider
Enables a divide-by-4 on the STATUS pin. This makes it easier to look at low duty-cycle signals out of the
R and N dividers.
[7] = 0; divide-by-4 disabled on STATUS pin (default).
[7] = 1; divide-by-4 enabled on STATUS pin.
01A
[6]
Ref freq monitor
threshold
Sets the reference (REF1/REF2) frequency monitor’s detection threshold frequency. This does not affect the VCO
frequency monitor’s detection threshold (see Table 17, REF1, REF2, and VCO frequency status monitor parameter).
[6] = 0; frequency valid if frequency is above 1.02 MHz (default).
[6] = 1; frequency valid if frequency is above 8 kHz.

Selects the signal that is connected to the LD pin.
