5.12 Frequency Synthesizer

5.12.1 VCO, Charge Pump, and PLL Loop Filter

The VCO is completely integrated and operates in the 1608 to 1880 MHz range. A frequency divider is

used to get a frequency in the UHF range (402 to 470 and 804 to 960 MHz). The BANDSELECT bit in the

ANALOG register selects the frequency band.

The VCO frequency is given by Equation 24.
