Use this manual in conjunction with the ASTRO Digital XTL 1500 VHF/UHF Range 1/UHF Range 2/ 700–800 MHz Mobile Radio Basic Service Manual (Motorola part number 6815854H01), which helps in troubleshooting a problem to a particular board.
Page 37 Introduction: General Included in other areas of this manual are functional block diagrams, detailed theory of operation, troubleshooting charts and waveforms, schematics, and parts list. You should be familiar with these sections to aid in deducing the problem circuit. Also included are component location diagrams to aid in locating individual circuit components, as well as IC diagrams, which identify some convenient probe points.
Page 38: Chapter 2 Product Overview
Chapter 2 Product Overview Introduction The ASTRO Digital XTL 1500 radio is a dual-mode (trunked/conventional), microcontroller-based transceiver incorporating a Digital Signal Processor (DSP). The microcontroller handles the general radio control, monitors status, and processes commands input from the keypad or other user controls.
Page 39: Control-Head Assembly
Product Overview: Control-Head Assembly Control-Head Assembly This section discusses the basic operation and components of the control-head assembly. 2.3.1 Controller The controller consists of three main components, namely the OMAP Applications Processor, Flash and SDRAM. The Applications Processor is the main controller of the control head. Its main function is to receive inputs from the user and relays the command to the transceiver microprocessor for processing via Serial Synchronous Interface (SSI) link.
Page 40: Keypad, Volume And Frequency Knob
Product Overview: Control-Head Assembly 2.3.3.2 Keypad, Volume and Frequency Knob The control head assembly processes all menu button inputs and visual indicators through the application processor. The buttons are programmable to allow different modes of operation through the CPS. All buttons are backlit to allow operation in low light. The volume knob allows a linear step of the volume and integrates the on/off function.
Page 41: Vehicle Interface Ports
Product Overview: Control-Head Assembly 2.3.4 Vehicle Interface Ports The Vehicle Interface Ports (VIPs) allow the control head to activate external circuits and receive inputs from the outside world. In general, VIP outputs are used for relay control. See the cable kit section for typical connections of VIP output relays.
Page 42: Receiver Section
Product Overview: Receiver Section Receiver Section This section discusses the receiver section components and basic operation for each band. 2.4.1 VHF Band Radios The VHF (136–174 MHz) receiver consists of a front-end and a back-end sections. 2.4.1.1 Front-End Section The primary function of the receiver front-end is to optimize image rejection and selectivity while providing the first conversion.
Page 43: Mhz Band Radios
Product Overview: Transmitter Section The back-end is primarily the ABACUS III digital IC. The ABACUS III IC uses a variable-bandwidth bandpass sigma-delta architecture. It is capable of down-converting analog as well as digital RF protocols into a baseband signal, which is then transmitted over the Synchronous Serial Interface (SSI) bus to the DSP and microprocessor.
Page 44: Rfpa
Product Overview: Frequency Generation Unit 2.5.3 700–800 MHz Radios The 700–800 MHz transmitter consists of an RF power amplifier (RFPA), output network (ON), and power control. 2.5.3.1 RFPA The RFPA is a three-stage, discrete-LDMOS transistor amplifier consisting of the following stages: first, driver, and final.
Page 45: Uhf Range 1/Uhf Range 2 Radios
Product Overview: Frequency Generation Unit • Associated circuitry The reference oscillator IC provides a frequency standard to the Fractional-N synthesizer IC, the ABACUS III digital back-end IC, and the controller section. The synthesizer turns on one of the four VCOs (determined by mode and band of operation) and tunes it to the receiver (RX) local oscillator (LO) or transmitter (TX) carrier frequency.
Page 46: Controller Section
Product Overview: Controller Section The voltage-controlled oscillator (VCO) module employs a Colpitts configuration with two bipolar stages in a common-base, common-collector configuration. The LC tank circuit's capacitive portion consists of a varactor diode, coupling capacitor, and a laser-trimmed capacitor for frequency adjustment.
Page 47: Digital (Astro) Mode Of Operation
2-10 Product Overview: Controller Section 2.7.2 Digital (ASTRO) Mode of Operation In the ASTRO mode (digital mode) of operation, the transmitted or received signal is limited to a discrete set of deviation levels, instead of continuously varying. The receiver handles an ASTRO- mode signal identically to an analog-mode signal up to the point where the DSP decodes the received data.
Page 48 Product Overview: Controller Section 2-11 The DSP section of microprocessor performs signaling, voice encoding/decoding, audio filtering, microphone gain and tuning, Private-Line/Digital Private Line (PL/DPL) encode, and alert-tone generation. It processes all baseband audio signals, providing pre-emphasis and signaling/filtering of the digital microphone audio data, as well as other transmitted signals. It also performs de-emphasis and decoding of received digital speaker audio and other received signals.
