Table 4.
Bit BS1 enables the BS1 port, the low band mixer and the low band oscillator. Bit BS2
enables the BS2 port, the mid band mixer and the mid band oscillator. When both BS1
and BS2 bits are logic 0, the high band mixer and the high band oscillator are enabled.
The oscillator signal is applied to the fractional-N programmable divider. The divided
