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.

What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency

|
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.
