VCO select. Selects one of three VCOs when VAS = 0, or selects the VCO starting
band when VASS = 0.
00 = Selects VCO1 (approximately 2200MHz to 2800MHz)
01 = Selects VCO2 (approximately 2800MHz to 3500MHz)
10 = Selects VCO3 (approximately 3500MHz to 4400MHz)
11 = VCO shutdown
VCO sub-band select. Selects one of 16 possible VCO sub-bands when VAS = 0,
or selects the VCO starting sub-band when VASS = 0.
0000 = Selects SB0
…
1111 = Selects SB15
VCO divider ratio select.
00 = Sets VCO divider to 4 (use when f
01 = Sets VCO divider to 8 (use when 275MHz < f
10 = Sets VCO divider to 16 (use when 137.5MHz < f
11 = Sets VCO divider to 32 (use when f
Sets the charge-pump current-selection mode between automatic and manual.
Must set to 1 for proper operation.
