							|  |  |  | 		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. |

							|  |  |  | 		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 |
