Reference Design Example
You must also observe the operating range limits:
(V[8:0] +8)
10MHz < 48MHz ·
(R[6:0] +2)
R[6:0] < 118

15:9 | RDW | Read/write | Reference divider word. Defines the binary value of | |
|
|
| the R[6:0] pins of the clock generator. | |
|
|
|
| |
8:0 | VDW | Read/write | VCO divider word. Defines the binary value of the | |
|
|
| V[8:0] pins of the clock generator. | |
|

Note
The default values for these registers set CLK1 to 25MHz and CLK2 to 12MHz.
