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 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.
