MC1322x Technical Data, Rev. 1.3
Freescale Semiconductor

impedance matching is also onboard. This combination allows for a very small footprint and a very low
cost RF solution.
The MC1322x also provides a secondary set of complementary PA outputs that can be used with external
RF circuitry such as a additional PA for higher TX power to the antenna. The single-ended port continues
as the receive input for this circuit configuration.
The receiver demodulator includes a module called the Differential Chip Detector which has two modes
of operation:
Non-coherent Detection (NCD) with automatic frequency control (AFC)
Non-coherent Differential Chip Detection (DCD) without AFC
The IEEE 802.15.4 standard allows a maximum clock drift of ±40 ppm (which equals ±80 ppm
station-to-station). The MC1322x 802.15.4 demodulator includes two different methods of operating in
the presence of such large frequency errors:
NCD Mode
Provides an increased ~3.5 dB of sensitivity. However, the addition of the AFC
increases the demodulator current drain about 3 mA.
DCD Mode
Default receive mode at lower current.
For longer range applications where external amplification may be desired (LNA and/or PA), additional
ports are provided for secondary complementary PA outputs. These can be used as a separate PA interface
while the single-ended port through the balun is used as an input only. Also, four control pins and a
regulated 20mA voltage source are provided to control external components and supply power to the PA
outputs.
The RF Interface functionality can be summarized as follows:
Programmable output power — 0 dBm nominal output power, programmable from -30 to +4 dBm
Receive sensitivity (at 1% PER, 20-byte packet) -
— < -96 dBm (typical) DCD receive (well above IEEE 802.15.4 specification of -85 dBm)
— < -100 dBm (typical) NCD receive (higher current)
Single-ended 50-
Ω antenna port — Uses integrated transmit/receive (T/R) switch, LNA, and
onboard balun. Impedance matching onboard.
Maximum flexibility — The optional single-ended port becomes RF input only and a separate set
of full differential PA outputs are provided. Separate input and outputs allow for a variety of RF
configurations including external LNA and PA for increased range
Four control signals for external RF components such as a LNA or PA
Regulated voltage source for PA biasing and powering external components
3.1.2
Modem
The modem supports the full requirement of the IEEE 802.15.4 Standard to transmit and receive data
packets. In additional, the mechanism is present to measure received signal level to provide CCA, ED, and
LQI as required by the 802.15.4 Standard.
