|  | 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. |
