2.4 RECM Control Hardware Theory of Operation 2.4.1 Control Logic The control logic interfaces to the keypad logic, transceiver, internal audio, and Motherboard. The control logic implements the main radio control function and all the baseband signal processing. TCVR Module DB25 Accessory Connector Keypad Board and Front Panel Interface Grey areas connect through the 80-pin connector on the Motherboard. Power Supply Figure 2-2: Guardian Control Logic 2.4.1.
2.4.1.2 On/Off Switching The main continuous supply 10V control is passed through a front panel on/off switch to generate 10V SW from the main radio supply. In normal operation the on/off switching is controlled by the radio on/off rotary switch by the control /RADON. Once switched on the main controller can hold the radio on by setting PWRHOLD. In addition to the radio rotary on/off switch, the on/off switching can be controlled by the external line /RADOFF via the accessory connector.
2.4.1.5 3.3V Linear Logic Supply The output from the 4.5V switch mode power supply is passed through 3.3V linear power supplies to remove any remaining power supply switching noise on the main logic supply. One 3.3V supply is used for control logic, the other 3.3V, 50 mA supply is used for control logic analog circuitry. 2.4.1.6 Reset Generator This circuit uses a MPU supervisory device (MAX825) to generate a reset pulse of at least 140 ms whenever the 3.3V logic supply drops below 3.08V.
LCDA0: LCD controller A0 command/ data select LCDCS: LCD chip select SCL: I2C and synthesizer clock DACSDA: Transceiver serial data, synthesizer, DAC, S-R SYNTHENA: Synthesizer framing pulse DACENA: DAC framing pulse SRENA: S-R framing pulse /DINT: Interrupt to DSP from H8 /RESO: Watchdog output from H8 2.4.1.
2.4.6 FPGA The control logic uses an Altera 8282 FPGA device to provide a flexible serial data routing function, I/O expansion for H8 and DSP, clock generation, data multiplexing, and to absorb discrete logic functions. The synchronous serial bus routing function involves routing the synchronous serial port of H8 either to the keypad and LCD, or to the I/O expansion in the FPGA. High-order address pins from H8 control this routing and a FPGA dummy write with dedicated FPGA chip select from H8.
2.4.14 Test Interface The test interface provides the following functions: Joint test action group (JTAG) connector access for board test and Flash boot sector programming Board reset and control access Board power supply and on-off switching access H8 serial debug port access 2.4.15 LED The control logic incorporates a 3-color LED used for status information. It is controlled by the FPGA to show red, green, or off. It is optically coupled to the top face of the radio by a light pipe.
2.5.1.3 PIN Diode Switch The antenna PIN diode switch is made up of CR7, CR8, CR9, CR10, and other associated components. This switch is a four-port design. The four ports are antenna 1 (TOP RF), antenna 2 (SIDE RF), receive, and transmit. Receive and transmit ports can be switched to only one of the two antenna ports. Transmit signals are routed from the transmit/receive PIN diode switch (to be discussed in the following paragraph) to the antenna port.
There are two 45 MHz IF amplifier circuits. The first (Q2, T2, etc.) utilizes loss-less feedback to deliver reasonable gain, low-noise figure, and a high third order intercept point simultaneously. Typical gain is 10.5 dB for the first IF amplifier. There are two crystal BPFs and a second 45 MHz IF amplifier. The BPFs provide attenuation for the adjacent and alternate channels, and also for the second image response. FL1 is a four-pole crystal filter with a 20 kHz bandwidth centered at 45 MHz.
U22 is the reference oscillator temperature sensor used to monitor the temperature near Y2. Its output is labeled XTALTEMP on the schematic diagram. This line is normally monitored by the microprocessor so the reference oscillator can be adjusted for drift due to changes in temperature. 2.5.2.2 Receive/Transmit VCOs and Buffer Amplifiers The receive VCO operates from 181 to 219 MHz since high side LO injection is used and the first IF is 45 MHz. The transmit VCO operates from 136 to 174 MHz.
2.5.3 Digital/Analog Control Digital/analog control is shown on page 1 of the RECM schematic. The transceiver is fitted with an EEPROM (U15). The IC is used to store calibration and curve fit data, which is needed when the transceiver is configured with the Guardian radio. Each transceiver has its calibration and curve fit data stored within the EEPROM. The calibration and curve fit data is written to the EEPROM at the successful conclusion of level 2 testing.
configured for a voltage gain of 2. The outputs at U2-1 and U6-1, labeled PABIAS1 and PABIAS2 respectively, are then routed to the gates of the power transistors. The correct DAC values for the bias current are stored in the EEPROM (U15). The correct DAC value is obtained and stored in the EEPROM during the power amplifier bias calibration procedure at level 2 testing.
2.6.2.1 Voltage Regulator and 7.8V On/Off Switch Linear regulator U5 provides +7.8V to the RF power control circuitry and to the other two PC assemblies in the control head. The regulator is powered via Q10 body diode at all time. When the unit is turned off all the circuits are disconnected from power except the transceiver in the control head. The transceiver in this case is in the off state. The power consumption in this case is less than 2 mA powering the boat backup memory circuits. 2.6.
2.6.6 PA ON/OFF Control (Bypass Mode) It is possible to operate the system not utilizing the PA (PA in by pass mode.) This is done by turning on control head on with the PTT depressed. An orange TX light indicates to the user that he is operating in by pass mode. In this mode, output power is about 1dB lower that the nominal levels delivered from the transceiver, as indicated in the table above. In normal mode, Q16 conducts at start-up, causing Q14 to conduct, which keeps Q15 off.
2.7 Display Board The Display board consists of a seven-switch keypad and an LCD module with integrated LED blue backlight. The board is heatstaked onto the plastic front panel, forming a permanent assembly. Electrical connections are made to the Interface board via a 20-pin connector (J13). The radio display module is a full graphics 80x32 pixels LCD, requiring a temperature compensated differential driving voltage of about 12V and a 1/6 bias, 1/32 duty cycle driving scheme.
2.7.1 Control Logic Interface The signals on this interface need not be filtered, but are protected from short circuits to ground. All logic signals are at 0 to 3V Complimentary Metal-Oxide Semiconductor (CMOS) levels at the interface. The interface carries the following functions: • • • • • • • • • • • • • 10V Control Ground /RADON Switched 10V Supply Reset AVR Clock Serial Data Clock Serial Data Input Serial Data Output Key Interrupt LCD Chip Select LCD A0 (data\command select) Keypad Chip Select 2.7.
PTT processing: In normal operation, a PTT switch closure causes Q2 to conduct, which in turn causes Q7 to conduct. This signal is distributed to the rest of the radio as the PTT signal. When a DTMF button is depressed, the transceiver automatically transmits this tone. PTT lockout: To prevent transmission of DTMF tone during programming, a latch circuit is provided to lockout PTT. When the ENTER button is pressed the PTT signals is disabled by a latches circuit.
CHAPTER 3: SOFTWARE THEORY OF OPERATION 3.1 Functional System Operation 3.1.1 General All control and channel software is resident in the RECM. 3.1.
3.1.3 Architecture A single digital signal processor (DSP) handles all signal-processing functions. An H8 microcontroller is used to control the user interface and implement other radio control functions. All references to signal names relate to the Receiver/Exciter/Control Module (RECM). Functionality partitioning is shown in Figure 1-1. 3.1.4 Board Identification The control logic stores an electronic serial number and modification status within nonvolatile storage on the board. 3.1.
The DSP pages-in different program images from the Flash for different modes of operation. Typically one image is used for receive and standby modes, but a new image is needed for transmit and key management operations. The DSP can interrupt the H8 controller, and then pass data over the host port back to H8.
Mode TX/RX (SR bit 7) STD/SIDE (SR bit 8) CTX (FPGA output) 3.2.3.2 Description Set in active transmit mode, front end TX/RX control Set to use radio antenna, reset to use accessory connector RF port Set in active transmit mode to enable the RF power amplifier Frequency Control The frequency of operation in both transmit and receive is controlled by the H8 setting in the synthesizer through the serial bus.
3.2.3.8 Receiver Scanning In some scanning modes it is necessary for the radio to scan a number of channels looking for traffic, as controlled by the H8 software. The basic requirement is to change the synthesizer frequency, RXVTF, synthesizer tune DAC, and to resume searching on the new frequency. The DSP may have to be informed of new traffic settings on which to search, for each new frequency. Scanning is interrupted when the DSP detects a signal of interest. 3.2.
3.2.6.1 Audio and Power Supply Unit (PSU) Driver A serial interface driver controls the output bits of a serial-to-parallel output shift register in the FPGA. Clock and data source for this shift register is the same serial port used for the user interface serial bus, but data is directed to the shift register using high-order H8 address lines. 3.2.6.2 Transceiver Serial Bus Driver A serial interface driver controls the transceiver shift register, DAC, and synthesizer.
Project 25 Voice Module VOICE Audio Processing Module Audio CODEC DTMF Tones CVSD DES Module Analog FM Module Transceiver Modulation Module Figure 3-2: Transmit DSP Chain 3.3.1.4 CVSD DES Module Audio data from the Audio Processing module is sent to the audio circular buffer. The sample rate is increased from 8 ksps to 12 ksps. The CVSD encodes the data and sends it to the transmit CVSD audio circular buffer.
3.3.1.7 Transceiver Interface The transceiver DAC has four output ports, two of which modulate the carrier. One of the two channels maintains carrier frequency accuracy. On transmit channel changes, the controller provides the DSP with two fractional values used to scale the two signals output from the DAC. The controller provides the DSP with an additional integer value at one second intervals, and is added to one of the DAC output signals to control carrier frequency accuracy.
filter is applied to the IQ data stream. Calculating the angular difference between consecutive IQ pairs demodulates the received signal. 3.3.2.2.1 Analog to Digital Converter Because the signal BW is much less than the 455 kHz carrier frequency, the ADC sub-samples the 455 kHz IF producing a frequency translation as part of the sampling process. The ADC sampling rate is 96 ksps. 3.3.2.2.
upper path signal removes the dc component from the upper path signal. Following this, the resulting signal passes through a single-bit quantizer and the output buffered for use by the code removal step. Data extraction and DCS code comparisons are then accomplished. 3.3.2.3.3 CVSD DES Detection Detection of CVSD DES waveform is performed by a secure detection function. This function also recovers the 12 kbps bit stream from the 48 ksps input signal.
3.3.3 DSP Software The program data for the DSP is stored in 64K Flash program blocks. The data is stored as unpacked bytes. The blocks used for the DSP software are dedicated so that selective upgrades of this code only are possible. 3.4 Keypad MPU Software 3.4.1 Overview The keypad microprocessor unit (MPU) provides an indirect interface via the Motherboard to the DTMF keypad and front panel switches. It communicates with the main controller via a synchronous bi-directional serial link. 3.4.

3.5.3.3 CAI Receive Voice Mode The DSP takes the 9.6 kbps CAI-compatible data stream and framing, and splits out the voice data for passing to the VOCODER. The DSP decodes the link control words so that the host H8 can read the link control fields, and the encryption synchronization information is available to the encryption process. CAI receive processing is initiated by the frame synchronization correlator trigger.
3.5.5 Receive Physical Link Layer This software uses common FM demodulation software, and mode-dependent receiver physical layer software modules. 3.5.5.1 Receive ADC and DAC Interface In receive modes SSI port 1 is used in a duplex manner to allow the ADC to be read continuously at 96 kHz and the DAC written up to 48 ksps for AGC and reference oscillator adjustment. In receive modes, the SSI port is clocked at 1536 kHz from an external clock source, using a 16-bit cycle.
3.5.6.2 CAI Encryption The DSP software uses DES kernel software to implement the CAI encryption of voice traffic as described in TIA/EIA/IS-102.AAAA. The key manager supplies the encryption key. In transmit, the message indicator (MI) vector is passed to data link processing for encoding and transmission. In receive, the data link layer decodes the MI vector, and fly wheeled if decoding fails for up to n frames. 3.5.6.
3.5.10 Hardware Control The DSP software controls the DSP clock rate through the phased locked loop (PLL) output divider. The DSP clock rate is dynamically matched to the mode of operation, in coarse steps for example, between searching and tracking receive modes. The DSP software uses low-current wait modes in pauses between processing to minimize current consumption. The host is also able to request a very low-current idle mode in the DSP. The host releases this mode. 3.6 Controller Software 3.6.
3.6.2.2.1 Interrupt Sources The following interrupt sources are used in H8. Interrupt Source User interface DSP Low dc voltage Timer PC serial port UI serial port Debug serial port Alarm generator Description External interrupt from the keypad External interrupt from the DSP, signal detected, etc.
3.6.2.3.2 Full Start-Up Software If a valid H8 program image exists, the full start-up code executes. This involves initializing RAM, DSP, keypad, user interface, FPGA, transceiver, etc., executing the start-up BIT, and transferring control to the main scheduler. 3.6.2.3.3 FPGA Configure Software At start-up H8 configures the FPGA using data from the main Flash memory and transferring it via a synchronous serial bus to the FPGA. 3.6.2.
3.6.3.1.4 Transceiver EEPROM The radio transceiver has an 8k x 8 serial EEPROM for storing transceiver calibration data. This data is set during production testing for the specific transceiver. The data in this device is essentially constant and is never written to by the main controller. At switch on, contents of the EEPROM are copied into the external RAM; EEPROM is not accessed during normal operation. 3.6.3.2 Data Types The controller software uses a number of different data types. 3.6.3.2.
All transfers and operations on the fill port are cyclic redundancy checked (CRC) and acknowledged. 3.6.4.2.1 Cloning The radio can export channel data to other radios. Data export is initiated by a user interface operation at the exporting radio. The exporting radio emulates a PC programmer during the data transfer. Cloning of keyfill data is not allowed. 3.6.4.2.2 Radio Keyfill The DSP software manages the radio keyfill protocols. 3.6.4.
CHAPTER 4: INSTALLATION, ADJUSTMENT, AND OPERATION 4.1 Radio Configuration 4.1.1 Channels A channel consists of a receive and transmit frequency pair. The radio has a total of 256 selectable channels. Each channel can be programmed for different receive and transmit frequencies, squelch, modulation, encryption, and power. Each channel can have one of possible 16 keys assigned on a channel-by-channel basis. An 8-character alphanumeric label identifies each channel or by its channel number if no text label.
4.3.5 Radio Power Up Turn on the radio using the on/off/volume knob. The radio performs a self-test and sounds a short medium-pitched tone to indicate PASS. Use the switch to set the volume to a comfortable level. Select the desired channel using the channel select switch. The process takes 3 to 5 seconds before the radio is ready for operation. 4.3.6 Choose a Channel The default display shows the current zone and channel. Use the channel select switch to select a different channel in the zone.

The receiver demodulates analog or digital voice and data signals.
5.4.3 Zeroize The radio can be programmed using an optional, external emergency key to zeroize all encryption keys. Using the programming menu, the radio can also zeroize all encryption keys, or selectively zeroize individual encryption keys. The emergency key is programmed using the PC programmer.
CHAPTER 6: SERVICING THE RADIO 6.1 General There are no user serviceable parts in the Guardian radio. Return it for servicing to the manufacturer after requesting an RMA number. Attempts to service the Guardian radio by non-authorized personnel voids the warranty. 6.2 Self-Test at Power Up At radio switch-on, the H8 controller executes a number of tests to confirm correct operation. Any errors are reported to the user through displayed error messages and logged in the Flash.
