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.
