Product Overview: Control-Head Assembly 2.3.2.7 DEK Interface With Radio: Remote-Mount (W4, W5, W7, W9) A maximum of three DEKs can be daisy chained to a single mobile radio. DEKs are only used with the W4, W5, W7, and W9 control heads when they are remotely mounted on the radio. DEKs are not used with any dash-mount control heads, including W4, W5, W7, or W9.
Page 60: 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 61: 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 62: Rfpa
2-10 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 63: Uhf Range 1/Uhf Range 2 Radios
Product Overview: Frequency Generation Unit 2-11 • 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 64: Controller Section
2-12 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 65: Digital (Astro) Mode Of Operation
Product Overview: Controller Section 2-13 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 66 2-14 Product Overview: Controller Section 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.

Page 133: Reset Circuits
Theory of Operation: Controller Section 3-67 3.8.4 Reset Circuits The reset circuits consist of the power-on reset (POR*) circuit (Figure 3-46), SW_B+ sense circuit, and SB9600 bus reset circuit. These circuits allow the microprocessor to recover from an unstable condition, such as removing battery A+ from the radio while it is on, battery voltage too low, and miscommunication to remote devices on the SB9600 bus, as well as generally monitoring the power on/off condition.
Page 134: Power-Up/Power-Down Sequence
3-68 Theory of Operation: Controller Section The other signal that can cause a processor/radio reset is the SB9600 RESET line. The RESET line is driven high (5 V) by a remote device that is having problems communicating with the processor. 3.8.5 Power-Up/Power-Down Sequence The XTL 5000 radio power is cycled via SW_B+ (battery voltage level).
Page 135: Usb Bus
Theory of Operation: Controller Section 3-69 The Patriot IC also requires a 32 kHz square-wave clock, provided at the CKIL (J7) pin. This clock is generated by a 32 kHz crystal (Y0100), with supporting circuitry for oscillation. This clock is utilized only for the Patriot IC, and is used for reset capability and other Patriot IC functions.
Page 136: Table 3-14. Rear Connector Naming Scheme
3-70 Theory of Operation: Controller Section This radio meets EIA compatibility with external data accessory devices. The naming scheme (see Table 3-14 Table 3-15) used for the microcontroller's RS-232 lines sometimes conflict with EIA RS-232 naming schemes. This is due to the microcontroller's pin names versus I/O direction, compared to the EIA pin names versus I/O direction.
Page 137: Serial Communications On The External Bus (Sb9600)
3.8.8 Serial Communications on the External Bus (SB9600) The SB9600 bus is an asynchronous serial communication bus using a Motorola-proprietary protocol. It provides a means for the microcontroller within the Patriot IC (U100) to communicate with other hardware devices. In the radio, it communicates with hardware accessories connected to the accessory connector and the remote interface board.

3-74 Theory of Operation: Controller Section The audio power amplifier (U0204), is a DC-coupled-output, bridge-type amplifier. The gain is internally fixed at 40 dB. Speaker audio leaves U0204 on pins 4 and 6. For dash-mount radios, the audio is routed to the speaker via J0402, pins 19, 21, 23, and 25, and then to J2, pins 20 and 26. The amplifier is biased to one-half of the A+ voltage.

(U102) located on the daughtercard. Reflashing is accomplished by using a programming cable (HKN6155 for Mid Power or HKN6183 for High Power) and the Motorola Customer Programming Software (CPS) FLASHport tool. The technique to flash the radio is the same as when using CPS or the TUNER software to change features on your radio.
Page 142: Reflashing/Upgrading Firmware
3-76 Theory of Operation: Controller Section The standard method of upgrading a radio's software and communicating between a computer and the radio microcontroller involves the use of the UART path via the programming cable. The radio is placed in a bootstrap mode whenever the programming cable is inserted into either the control- head microphone connector (P104) or the remote-mount interconnect board data connector (P506).

The daughtercard module is tested prior to placement on the main board. However, this is done with proprietary software that is not available outside Motorola. Also, because of the high density of the solder balls, the pins of the three ICs are not exposed to the outside world for test probing.
