+Description:
+ Stores channel Y frequency resolution/channel spacing in Hz for PLL
+ devices. The given value directly influences the operating mode when
+ fractional-N synthesis is required, as it derives values for
+ configurable modulus parameters used in the calculation of the output
+ frequency. 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.
