MODE CONTROL AND INTERFACE LINES

1 XCEN

I (CMOS)

Enables the bandgap reference and

voltage regulators when high. Consumes

only leakage current in STANDBY mode

when low. This is a CMOS input, and the

thresholds are referenced to VDD and

VSS.

2 RXON

I (CMOS)

TX/RX Control Input. Switches the

transceiver between TRANSMIT and

RECEIVE modes. Circuits are powered

up and signal paths reconfigured

according to the operating mode. This is

a CMOS input, and the thresholds are

referenced to VDD and VSS.

RXON 2

DIN 30

3 PAON

O (CMOS)

PA Control Output. Enables the off-chip

PA at the correct times in a Transmit slot.

Goes high when transmit RF is present

at TXO; goes low 5μs before transmit RF

is removed from TXO. Has interlock logic

to shut down the PA if the PLL does not

lock.

9 FREF

I

Input for the 9.216MHz, 12.288MHz,

18.432MHz or 25.576MHz reference

frequency. This input is used as the

reference frequency for the PLL and as a

calibration frequency for the on-chip

filters. An AC-coupled sine or square

wave source drives this self-biased input.
