VCO Autocalibration

The VCO uses an autocalibration technique to select the correct

VCO and band, as explained in the Voltage-Controlled Oscillator

(VCO) section. Register CR24, Bit 0, controls whether the auto-

calibration is enabled. For normal operation, autocalibration needs

to be enabled. However, if using cumulative frequency steps of

100 kHz or less, autocalibration can be disabled by setting this

bit to 1 and then a new acquisition is initiated by writing to

Attenuator

The attenuator can be programmed from 0 dB to 47 dB in steps

of 1 dB. Control is through Register CR30, Bits[5:0].

Revision Readback

The revision of the silicon die can be read back via Register CR33.
