  • Page 36 3-10 Theory of Operation: Transceiver Section 3.1.3.6.1 Power and Control Since U104 is powered from switched B+, it makes its own regulated 4.5 Vdc to power the internal logic. The supply input is V5EXT at pin 17, and the output is V45 at pin 16. RX at pin 23 is the control signal to the antenna switch control circuit.
  • Page 37 DSP and the analog modulation input of the FracN IC. 3.1.4.2 Fractional-N Frequency Synthesizer (FracN) IC U202 The FracN IC, U202, is a mixed-mode, Motorola-proprietary, CMOS, fractional-N frequency synthesizer with built-in dual-port modulation. The XTS 4000 radio uses a low-voltage version of the device, sometimes called LVFracN, for compatibility with the 3 V logic used throughout the radio.
  • Page 38 3-12 Theory of Operation: Transceiver Section 3.1.4.2.3 Modulation To support many voice, data, and signaling protocols, XTS 4000 radios must modulate the transmitter carrier frequency over a wide audio frequency range, from less than 10 Hz up to more than 6 kHz. The FracN supports audio frequencies down to zero Hz by using dual-port modulation. The audio signal at pin 10 (MODIN) is internally divided into high- and low-frequency components, which modify both the synthesizer dividers and the external VCOs through signal MODOUT (pin 41).

    Glossary Glossary-1 Glossary Glossary This glossary contains an alphabetical listing of terms and their definitions that are applicable to ASTRO portable and mobile subscriber radio products. All terms do not necessarily apply to all radios, and some terms are merely generic in nature. Term Definition See analog-to-digital conversion.
  • Page 196 Glossary-2 Glossary Term Definition CODEC See coder/decoder. codeplug Firmware that contains the unique personality for a system or device. A codeplug is programmable and allows changes to system and unit parameters. See also firmware. coder/decoder A device that encodes or decodes a signal. See Customer Programming Software.
  • Page 197 FLASHcodes are only applicable for radios which are upgradeable through the FLASHport process. FLASHport A Motorola term that describes the ability of a radio to change memory. Every FLASHport radio contains a FLASHport EEPROM memory chip that can be software written and rewritten to, again and again.
  • Page 198 Glossary-4 Glossary Term Definition frequency Number of times a complete electromagnetic-wave cycle occurs in a fixed unit of time (usually one second). frequency This unit generates ultra-stable, low-phase noise master clock and other generation unit derived synchronization clocks that are distributed throughout the communication network.
  • Page 199 SPI data line from a peripheral to the MCU. Master Out Slave In SPI data line from the MCU to a peripheral. See microcontroller unit. Motorola Digital Communications. MCU/DSP Interface internal to the Patriot IC. See Megahertz. Megahertz One million cycles per second. Used especially as a radio-frequency unit.
  • Page 200 Data transmitted on the control channel from the central controller to the word subscriber unit. over-molded pad- A Motorola custom IC package, distinguished by the presence of solder array carrier balls on the bottom pads. over-the-air rekeying Allows the dispatcher to remotely reprogram the encryption keys in the radio.
  • Page 201 Glossary Glossary-7 Term Definition read-only memory A type of computer memory on which data has been prerecorded. Once data has been written onto a ROM chip, it cannot be removed and can only be read. real-time clock A module that keeps track of elapsed time even when a computer is turned off.
  • Page 202 Glossary-8 Glossary Term Definition Serial Peripheral How the microcontroller communicates to modules and ICs through the Interface CLOCK and DATA lines. signal An electrically transmitted electromagnetic wave. Signal Qualifier An operating mode in which the radio is muted, but still continues to mode analyze receive data to determine RX signal type.
  • Page 203 Glossary Glossary-9 Term Definition thin small-outline A type of dynamic random-access memory (DRAM) package that is package commonly used in memory applications. time-out timer A timer that limits the length of a transmission. See time-out timer. transceiver Transmitter-receiver. A device that both transmits and receives analog or digital signals.
