3.3.4 RF Divider

The RF divider delivers the local oscillator signal to the mixer in RXMode or the transmit frequency to the power amplifier in TXMode by dividing the VCO output frequency by 2, 4 or 6. It divides by 6 for 310 MHz to 318 MHz, by 4 for 418 MHz to 477 MHz and by 2 for 836 MHz to 956 MHz. The RF divider is controlled by the FECR.S4N3 and FECR.LBNHB control bits.
