| What: /sys/bus/iio/devices/iio:deviceX/out_altvoltageY_frequency |
| KernelVersion: |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Stores the PLL frequency in Hz for channel Y. |
| Reading returns the actual frequency in Hz. |
| The ADF4371 has an integrated VCO with fundamendal output |
| frequency ranging from 4000000000 Hz 8000000000 Hz. |
| |
| out_altvoltage0_frequency: |
| A divide by 1, 2, 4, 8, 16, 32 or circuit generates |
| frequencies from 62500000 Hz to 8000000000 Hz. |
| out_altvoltage1_frequency: |
| This channel duplicates the channel 0 frequency |
| out_altvoltage2_frequency: |
| A frequency doubler generates frequencies from |
| 8000000000 Hz to 16000000000 Hz. |
| out_altvoltage3_frequency: |
| A frequency quadrupler generates frequencies from |
| 16000000000 Hz to 32000000000 Hz. |
| |
| Note: writes to one of the channels will affect the frequency of |
| all the other channels, since it involves changing the VCO |
| fundamental output frequency. |

| KernelVersion: |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Reading returns the datasheet name for channel Y: |
| |
| out_altvoltage0_name: RF8x |
| out_altvoltage1_name: RFAUX8x |
| out_altvoltage2_name: RF16x |
| out_altvoltage3_name: RF32x |

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