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

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