Detailed Description

RFTX_PLLCTRL: PLL frequency control

NF , NX: Control the frequency multiplication ratio of the PLL. The RF transmit frequency will by fXTL * a multiplication ratio which is: If FRAC_EN is 1 then: 8 + nx (integer-N mode) If FRAC_EN is 1 hen: 9 + nx + nf/(2^14) (fractional-N mode)

DF: Frequency deviation of the logic 1 level in FSM mode. This number is added to NF during the logic 1 chips in FSK mode. Ignored in other modes.

LPFTRIM: Loop filter trim for PLL. Recommended value is 4'b0011.

CPTRIM: Charge pump trim for PLL. Recommended value is 3'b001.
