    Controller Section Theory of Operation: Power Control Power Control (Refer to schematic Page 10-24 for reference) The power control loop regulates RF output power with an automatic level control (ALC) loop and provides protection features against overcurrent, excessive control voltage, and high operating temperatures.

  • Page 90: Protection Features

    Controller Section Theory of Operation: Power Control Rise and fall time is controlled by the D/A adjustable control voltage limit circuit attached to the reference voltage at U0550 pin 10 via transistor Q0555. The reference voltage at U0550 pin 10 is pulled low by Q0555 when the PA control voltage approaches the limit set by the D/A output PA CNTL LIM, U0551 pin 13.

  • Page 91: Interfacing

    Controller Section Theory of Operation: Interfacing The D/ A line CUR LIM SET at U0551 pin 4 adjusts the maximum allowed current by creating an offset voltage equivalent to the voltage drop across the sense resistor (R5612). For all models (except UHF1 110W and UHF2 40W), CUR LIM SET connects to the non-inverting input of U0550-2 (pin5) through resistors R0547 and R0583, reducing the voltage at the non-inverting input sufficiently to make the non-inverting and inverting inputs equal at the desired current drain.

  • Page 92: Serial Peripheral Interface (Spi)

    7-10 Controller Section Theory of Operation: Interfacing Serial Peripheral Interface (SPI) (Refer to Controller schematic page 10-23 for reference) The µP communicates to many of the ICs through its SPI port. This port consists of SPI TX DATA (U0103-66), SPI RX DATA (U0103-65), CLK (U0103-67) and chip select lines going to the various ICs, connected on the SPI PORT (BUS).

  • Page 93: Sb9600 Serial Interface

    Controller Section Theory of Operation: SB9600 Serial Interface 7-11 When the µP needs to program any of these ICs it brings the chip select line for that IC to a logic 0 and then sends the proper data and clock signals. The amount of data sent to the various ICs are different, for example the ASFIC can receive up to 21 bytes (168 bits) while the ZIF can receive up to 5 bytes (40 bits).

  • Page 94: General Purpose Input/Output

    7-12 Controller Section Theory of Operation: MicroprocessorOperation An option can reset the radio by driving the LH RESET line to a logic 1. This gets buffered by Q0409 and Q0425 and goes to the reset input of SLIC (U0104-A8). This then causes the reset input of the µP (U0103-50) RESET to go to a logic 0 resulting in the µP restarting operation.
  • Page 95 Controller Section Theory of Operation: MicroprocessorOperation 7-13 The external EEPROM (U0100) as well as the µP’s own internal EEPROM space contain the information in the radio which is customer specific, referred to as the codeplug. This information consists of items such as: 1)what band the radio operates in, 2)what frequencies are assigned to what channel, and 3) tuning information.
  • Page 96 7-14 Controller Section Theory of Operation: MicroprocessorOperation U0103-30 is the high reference voltage for the A/D ports on the µP. Resistor R0112 and capacitor C0104 filter the +5 V reference. If this voltage is lower than +5 V the A/D readings will be incorrect. Likewise U0103-29 is the low reference for the A/D ports.
  • Page 97 Controller Section Theory of Operation: MicroprocessorOperation 7-15 The FLASH EEPROM (U0106) contains the radio’s operating software. This software is common to all radios within a given model type. For example Securenet radios may have a different version of software in the FLASH ROM than a non-secure radio. This is, as opposed to the codeplug information stored in EEPROM (U0100) which could be different from one user to another in the same company.

    7-16 Controller Section Theory of Operation: Audio and Signalling Circuits Bootstrap Microprocessor Operation The bootstrap mode of operation is only used to load new software into the FLASH EEPROM (U0106 or U0102). The MODA (U0103-33) and MODB (U0103-32) inputs must be a logic 0 when the microprocessor comes out of reset.

There are 6 enable lines on the Hear Clear IC which determine its mode of operation.

    Chapter 8 Control Heads Model I Introduction The Control Head forms the interface between the radio and the user. It contains an LCD display, on/ off and volume switch, keypad and control keys. The microprocessor controlled Control Head interfaces to the radio control logic board J0650 via an 18-pin connector on the back of the unit.

  • Page 112: Lcd

    Control Heads: Model I Backlight The backlight consists of 10 LEDs. Light intensity is in 3 levels including off and is software controlled by bus commands via µC U0653. Driver The LCD driver U0651 contains the default character set. Its interface is a four line serial interface. The LCD driver is connected to the µC on pins PA0 - PA3.

  • Page 113: Models Ii And Iii

    Control Heads: Models II and III When the connected device is an SB9600 device, the current is greater than 2 mA and the multiplexer is switched to SB9600 mode. Note that when an SB9600 device is self-powered, i.e. no current consumption from the microphone connector, a dummy load must be connected to pin 1 to ensure a minimum current of 2 mA and force the multiplexer into the SB9600 mode.

  • Page 114: Audio Configuration

    Control Heads: Models II and III Audio Configuration The Control Head can be configured for Handset audio or Speaker+ which is a balanced output from the radio. Handset audio is configured by inserting R0665 in the line from pin 8 to the microphone connector.

    Control Heads: Models II and III Display Display (H0650) is a double layer super twist LCD display. Control Head model II has one line of 14 characters with fixed symbols on top, six key-related symbols on the bottom and RSSI symbol on the right-hand side.
  • Page 116 Control Heads: Models II and III In the Secure keyload mode, an A/D input on the µC U0653 (PD6) monitors the Speaker-output dc voltage. If the output is short circuit to ground for more than 1 second, the µC senses this via R0689/ R0690 network and switches the multiplexer to keyload mode via U0654 (Q1).
