- What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_resolution
- KernelVersion: 3.4.0
- Contact: linux-iio@vger.kernel.org
- 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
- KernelVersion: 3.4.0
- Contact: linux-iio@vger.kernel.org
- 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.
