associated with RFIN_x and PAO_x signal pairs. The RF interface allows both single port differential
operation and dual port differential operation.

Transceiver RF Configurations and External
Connections
Programmable output power — 0 dBm nominal output power, programmable from -27 dBm to +4
dBm typical
<-94 dBm (typical) receive sensitivity — At 1% PER, 20-byte packet (well above 802.15.4
Standard of -85 dBm)
Optional integrated transmit/receive (T/R) switch for low cost operation — With internal PAs and
LNA, the internal T/R switch allows a minimal part count radio interface using only a single balun
to interface to a single-ended antenna
Maximum flexibility — There are full differential RF I/O pins for use with the internal T/R switch.
Optionally, these pins become the RF_IN signals and a separate set of full differential PA outputs
are also provided. Separate inputs and outputs allow for a variety of RF configurations including
external LNA and PA for increased range
CT_Bias Output — The CT_Bias signal provides a switched bias reference for use with the internal
T/R switch, and alternatively can be programmed as an antenna switch signal for use with an
external antenna switch
Onboard trim capability for 16 MHz crystal reference oscillator — The 802.15.4 Standard puts a
+/- 40 ppm requirement on the carrier frequency. The onboard trim capability of the modem crystal
oscillator eliminates need for external variable capacitors and allows for automated production
frequency calibration. Also tighter tolerance can produce greater receive sensitivity
RF Interface Pins
shows the RF interface pins and the associated analog blocks. Notice that separate PA blocks are
also be initialized (even though they cannot be used) to prevent floating inputs.
