4Description:
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.

40Description:
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.
