+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 used to compute the various
+ dividers is able to generate proper values for multiples of the channel
+ spacing.
