3. Circuit description
The module consists mainly of the fully integrated CMOS transceiver and baseband processor
SC14441 from SiTel semiconductor intended for DECT 6.0 handsets and base stations. RF switches
and other components are added to the design in order to perform the desired functionality
required for DECT/GAP. Figure 1 shows the block diagram of the module.
The DECT transceiver/baseband SC14441
SC14441 is a 1.8V single chip for DECT applications containing a fully integrated radio transceiver
and baseband processor. It is designed to perform the complete transmit and receiver function.
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 SiTel
semiconductor.
