4 | Description: | |
5 | Stores channel Y frequency resolution/channel spacing in Hz. | |
6 | The value given directly influences the MODULUS used by | |
7 | the fractional-N PLL. It is assumed that the algorithm | |
8 | that is used to compute the various dividers, is able to | |
9 | generate proper values for multiples of channel spacing. | |

14 | Description: | |
15 | Sets channel Y REFin frequency in Hz. In some clock chained | |
16 | applications, the reference frequency used by the PLL may | |
17 | change during runtime. This attribute allows the user to | |
18 | adjust the reference frequency accordingly. | |
19 | The value written has no effect until out_altvoltageY_frequency | |
20 | is updated. Consider to use out_altvoltageY_powerdown to power | |
69078517 | 21 | down the PLL and its RFOut buffers during REFin changes. |
