Input/Output Modes
The TRF2432 is designed to control power and band status for a TI RFFE. The TRF2432 is designed to drive
external P-MOSFETs to power up and down the appropriate sections of the RFFE. Table 4 lists the various
modes of the TRF2432 and the input parameters required to enter each mode. The corresponding outputs to the
RFFE are also described. Figure 4 illustrates the power control interface and recommended P-MOSFET circuit.
SYNTHESIZER PROGRAMMING
The RF synthesizer frequency is programmed with four bytes: DR, SR, FR and MR and the crystal pre-scalar: P.
See digital interface characteristics for programming instructions). The RF PLL locking frequency is calculated
as follows:

REF
is the crystal reference frequency. On power-up the default register values (P=1, DR=10, SR=0, FR=48 and
MR=79) with a 40-MHz crystal will attempt to lock the RFLO to 2068 MHz. The valid register ranges are listed
