   3 Contact:        linux-iio@vger.kernel.org
   4 Description:
   5                 Stores the PLL frequency in Hz for channel Y.
   6                 Reading returns the actual frequency in Hz.
   7                 The ADF4371 has an integrated VCO with fundamendal output
   8                 frequency ranging from 4000000000 Hz 8000000000 Hz.

  10                 out_altvoltage0_frequency:
  11                         A divide by 1, 2, 4, 8, 16, 32 or circuit generates
  12                         frequencies from 62500000 Hz to 8000000000 Hz.
  13                 out_altvoltage1_frequency:
  14                         This channel duplicates the channel 0 frequency
  15                 out_altvoltage2_frequency:
  16                         A frequency doubler generates frequencies from
  17                         8000000000 Hz to 16000000000 Hz.
  18                 out_altvoltage3_frequency:
  19                         A frequency quadrupler generates frequencies from
  20                         16000000000 Hz to 32000000000 Hz.
  21
  22                 Note: writes to one of the channels will affect the frequency of
  23                 all the other channels, since it involves changing the VCO
  24                 fundamental output frequency.

  27 KernelVersion:
  28 Contact:        linux-iio@vger.kernel.org
  29 Description:
  30                 Reading returns the datasheet name for channel Y:
  31
  32                 out_altvoltage0_name: RF8x
  33                 out_altvoltage1_name: RFAUX8x
  34                 out_altvoltage2_name: RF16x
  35                 out_altvoltage3_name: RF32x

  37 What:           /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_powerdown
  38 KernelVersion:
  39 Contact:        linux-iio@vger.kernel.org
  40 Description:
  41                 This attribute allows the user to power down the PLL and it's
  42                 RFOut buffers.
  43                 Writing 1 causes the specified channel to power down.
  44                 Clearing returns to normal operation.
