System Controller Consists of a system microcontroller, radio modem, and provides serial communication interfaces. DRC (Diversity Continuously selects the receiver with the best signal level to supply recovered Reception Controller) modulation. Eliminates destructive effects of multi-path fading. Receiver Injection Creates injection signals used by the three (3) VHF (very high frequency) receivers to down-convert the carrier to an IF (intermediate frequency). VHF Receiver Provides reception and demodulation of FM (frequency modulated) VHF RF (radio frequency) signals. The receivers also provide RF carrier amplitude information used by the DRC. VHF Exciter Generates transmit carrier signals and performs frequency modulation. Power Amplifier Amplifies low-level exciter RF carrier signals to the final output power level. SECTION 1: THEORY OF OPERATION ~\Technical Documentation\System Manuals\FCC-Reports\IP1B-FCCRpt.doc Page 4 System Controller Block Diagram Functional block diagram of the System Controller. The system controller controls all programmable devices in the radio and handles internal and external communications. Microcontroller Description The base station uses a SGS/Thomson ST10F167 microcontroller. It is a highly integrated processor with many on chip peripherals including: • 128K bytes of on chip Flash EPROM for program storage • 4K bytes RAM • UART (asynchronous serial interface) • Synchronous serial interface • Analog-to-digital converter • General purpose timers • Watchdog timer • Reset generator • Programmable chip selects • Clock multiplier • General purpose I/O pins In addition to the microcontroller on chip memory, there are also 512K bytes of RAM for data buffers and system use, and 2K bytes of non-volatile memory for configuration information. Message Processing For down-link data transmissions, the microcontroller receives data from the serial port, determines the start and end of data frames, formats the data for transmission, turns on the transmitter, and passes the data to the transmit modem chip. At the end of the transmission, if no other messages are ready, the microcontroller turns off the transmitter. SECTION 1: THEORY OF OPERATION ~\Technical Documentation\System Manuals\FCC-Reports\IP1B-FCCRpt.doc Page 5 For up-link transmissions, the microcontroller receives data from the receive modem chip, checks for errors, adds framing and optionally signal strength information, and sends it out the serial port. Synthesizers The microcontroller is responsible for keeping the base station on channel by programming the digital PLL (phase-locked-loop) frequency synthesizers. This task is accomplished via a serial comm…

PRELIMINARY INFORMATION Features Applications • 4-Level Root Raised Cosine FSK Modulation • Half Duplex, 4800 to 19.2kbps • Increase Channel Bit Rate/Hz • Full Data Packet Framing • Impulse and NRZ Signal Modes • Enhanced Performance in Noisy Conditions • Error Detection and Error Correction • Low Power 3.3V/5.0V Operation • Wireless Data Terminals • Two Way Paging Systems • Digital Radio Systems • Wide Area Wireless Data Broadcasts • Point to Point Wireless Data Links MODEM DATA PUMP MX919B ANALOG TX DATA AND CONTROL BUS ANALOG RX RF RADIO DISCRIMINATOR MODULATOR SYSTEM APPLICATION PROCESSING HOST Cμ The MX919B is a low voltage CMOS device containing all of the baseband signal processing and Medium Access Control (MAC) protocol functions required for a high performance 4-level FSK Wireless Packet Data Modem. It interfaces with the modem host μC and the radio modulation/demodulation circuits to deliver reliable two-way transfer of the application data over a wireless link. The MX919B assembles application data received from the host μC, adds forward error correction (FEC) and error detection (CRC) information, and interleaves the result for burst-error protection. After automatically adding symbol and frame sync codewords, the data packet is converted into filtered 4-level analog signals for modulating the radio transmitter. In receive mode, the MX919B performs the reverse function using the analog signals from the receiver discriminator. After error correction and removal of the packet overhead, the recovered application data is supplied to the host μC. CRC detected residual uncorrected data errors will be flagged. A readout of the SNR value during receipt of a packet is also provided. The MX919B uses data block sizes and FEC/CRC suitable for applications where high-speed transfer of data over narrow-band wireless links is required. The device is programmable to operate at standard bit rates from a wide range of Xtal/clock frequencies. The MX919B may be used with a 3.0V to 5.5V power supply and is available in the following package styles: 24-pin SSOP (MX919BDS), 24-pin SOIC (MX919BDW), 24-pin PLCC (MX919BLH), and 24-pin PDIP (MX919BP). 4-Level FSK Modem Data Pump Page 2 of 47 MX919B PRELIMINARY INFORMATION ©2001 MX•COM, INC. www.mxcom.com Tele: 800 638 5577 336 744 5050 Fax: 336 744 5054 Doc. # 20480170.003 4800 Bethania Station Road, Winston-Salem, NC 27105-1201 USA All trademarks and service marks are held by their respective companies.
