This register configures the programmable-reference
frequency dividers for the synthesizers, and sets the
DC current for the charge pump. The programmable-
reference frequency divider provides the reference fre-
quencies to the phase detector by dividing the crystal
oscillator frequency (see Table 13).
This register configures the Rx/Tx calibration modes
(See Table 14).

Set D12:D11 = 11
These Bits Set the VCO Sub-Band when Programmed Using the SPI (D8 = 1). D10:D9 = 00: lowest
frequency band; 11: highest frequency band.
VCO SPI Bandswitch Enable. 0: disable SPI control, bandswitch is done by FSM; 1: bandswitch is
done by SPI programming.
VCO Bandswitch Enable. 0: disable; 1: start automatic bandswitch.
RF Frequency Band Select in 802.11a Mode (D0 = 1). 0: 4.9GHz to 5.35GHz Band; 1: 5.47GHz to
5.875GHz Band.
PLL Charge-Pump-Current Select. 0: 2mA; 1: 4mA.
Set to 0
These Bits Set the Reference-Divider Ratio. D3:D1 = 001 corresponds to R = 1 and 111
corresponds to R = 7.
RF Frequency Band Select. 0: 2.4GHz Band; 1: 5GHz band.
Set to 0 for Normal Operation. Set to 1 for MIMO applications.
