3. Circuit description
The module consists mainly of the fully integrated CMOS transceiver and baseband processor
SC14446 from Dialog semiconductor intended for DECT base stations. RF switches and other
components are added to the design in order to perform the desired functionality required for
DECT/GAP. The two equal antennas are PCB monopole antennas tuned for the actual frequency
range. Figure 1 shows the block diagram of the module.
The DECT transceiver/baseband SC14446
SC14446 is a 1.8V single chip for DECT applications containing a fully integrated ZBS radiotransceiver and baseband processor. It is designed to perform the complete transmit and receive
function in all slots (ZBS). The device is designed to operate the frequency synthesizer in a close
loop configuration both during transmit and receive mode. Logic output ports are used to control
the T/R switch and antenna switch for FAD (Fast Antenna Diversity). The CompactRISC CR
16Cplus microprocessor with a single wire debug port running from ROM controls the protocol
stack and the I/O peripherals, keyboard, UART, ACCESS bus, SPI, LED drivers and RF switches.
The audio path comprises a 16 bit CODEC with an analog frontend including a high efficiency 4
ohm audio amplifier (class D) and a programmable Gen2DSP supporting various
telecommunication algorithms. Detailed information about the chip is available from Dialog
semiconductor.
