| 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. |

| KernelVersion: 3.4.0 |

| 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. |
