1What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_resolution 2KernelVersion: 3.4.0 3Contact: linux-iio@vger.kernel.org 4Description: 5 Stores channel Y frequency resolution/channel spacing in Hz. 6 The value given directly influences the MODULUS used by 7 the fractional-N PLL. It is assumed that the algorithm 8 that is used to compute the various dividers, is able to 9 generate proper values for multiples of channel spacing. 10 11What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency 12KernelVersion: 3.4.0 13Contact: linux-iio@vger.kernel.org 14Description: 15 Sets channel Y REFin frequency in Hz. In some clock chained 16 applications, the reference frequency used by the PLL may 17 change during runtime. This attribute allows the user to 18 adjust the reference frequency accordingly. 19 The value written has no effect until out_altvoltageY_frequency 20 is updated. Consider to use out_altvoltageY_powerdown to power 21 down the PLL and it's RFOut buffers during REFin changes. 22
