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. |

|
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.
