  1. What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency_resolution
  2. KernelVersion: 3.4.0
  3. Contact: linux-iio@vger.kernel.org
  4. Description:
  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. What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_refin_frequency
  11. KernelVersion: 3.4.0
  12. Contact: linux-iio@vger.kernel.org
  13. Description:
  14. Sets channel Y REFin frequency in Hz. In some clock chained
  15. applications, the reference frequency used by the PLL may
  16. change during runtime. This attribute allows the user to
  17. adjust the reference frequency accordingly.
  18. The value written has no effect until out_altvoltageY_frequency
  19. is updated. Consider to use out_altvoltageY_powerdown to power
  20. down the PLL and its RFOut buffers during REFin changes.
