|
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:
|
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.
