    • Second IF amplifiers • FM Demodulator • Audio amplifier In addition to BBR IC, the back end contains the following components: • Second LO resonator for 44.645 MHz (Y5211) • Crystal filters for 455 kHz (FL5201, FL5202) • Demodulator filter (C5224) The IF signal routed to BBR IC is amplified, converted to 455 kHz, filtered, limited and demodulated.
  • Page 40: Power Control Circuitry

    This network forms a low-pass filter to attenuate harmonic energy of the transmitter to specifications level. A forward-power detector follows the harmonic filter. This forward-power detector is a microstrip printed circuit, which couples a small amount of the forward energy and sends it to diode CR6506 where it is rectified. This rectified signal (VFORWARD) forms the forward voltage which the power control circuit holds constant.
  • Page 41: Synthesizer Detailed Functional Description

    Synthesizer Detailed The complete synthesizer subsystem consists of a reference oscillator (U5700), a Fractional-N Synthesizer IC (U5702), two on-board voltage controlled oscillators, Functional Description a buffer stage (U5701), and two line-up amplifiers (Q5707, Q5705). Reference oscillator U5700 contains a temperature compensated crystal with an oscillation frequency of 16.8 MHz.
  • Page 42 The serial interface (SPI_DATA) is connected to the microprocessor via the data line (pin 5 of U5702), clock line (pin 6 of U5702), and chip enable line (pin 5 of U5702). Proper enabling of these lines should allow the microprocessor to load the synthesizer IC.
  • Page 43: Controller Detailed Functional Description

    The digital section consists of a microprocessor, memory ICs, glue logic circuitry, signal MUX ICs, On/Off circuit, and general purpose Input/Output circuitry. The controller is based on the Motorola 68HC11K1 microprocessor (U0101), 8- Kbyte SRAM (U0103), 128 Kbyte-OTP memory (U0102), and 4 Kbyte EEPROM (U0104).
  • Page 44: Electronic On/Off

    Diode D5601 located on the PA section acts as protection against transients and wrong polarity of the supply voltage. Electronic On/Off The radio has circuitry which allows radio software and/or external triggers to turn the radio on or off without direct user action. Some examples of where this is useful are: 1) automatic turn on when emergency switch is engaged;...
  • Page 45: Hook

    When the IGNITION input goes above 6 V, Q0450, Q0612 and Q0611 turn on, supplying SW B+ to the radio and enabling U0601 and U0631 to supply the regulated voltage (+5 V and 9.3 V) to all the circuitry. The µP starts to run the software, reads the line EMER IGN SENSE, determines from the level (Emergency has a different level) that the IGNITION input is active and sets the B+ CONTROL (via the ASFIC-GCB2) to high and latches SW B+ to on.
  • Page 46: Sbep Serial Interface

    SPI BUS is also used for the control head. U0106 buffers the SPI TRANSMIT DATA and CLK lines to the control head. U0106 serves also to switch off the CLK signal for the LCD display while it is not selected via LCD CE signal. When the µP needs to program any of these ICs, it drops down the chip select line of the specific IC to a logic 0 and then sends the proper data and clock signals.
  • Page 47: One-Time Programmable (Otp) Memory

    On the K1µP the lines XIRQ (U0101-30), MODA LIR (U0101-77), MODB VSTPY (U0101-76) and RESET (U0101-75) should be logic high during all normal K1µP operation. Whenever a data or an address line becomes unloaded or shorted to an adjacent line, a common symptom is that short negative pulses occur on the RESET line, with a period of 20 msec.
  • Page 48: Static Random Access Memory (Sram)

    access signals (SI, SO and SCK) are generated by the K1µP and chip select (CS) is generated by address decoder U0105. Additional EEPROM is contained in the K1µP (U0101). This EEPROM is used to store radio tuning and alignment data. Like the external EEPROM this memory can be programmed multiple times and will retain the data when power is removed from the radio.
  • Page 49: Controller Audio & Signaling Circuits

    Controller Audio & Signaling Circuits General Audio Signalling Filter IC The ASFIC (U0201) used in the controller has four functions; (ASFIC) • RX/TX audio shaping, i.e. filtering, amplification, attenuation • RX/TX signalling, PL/DPL/HST/MDC/MPT • Squelch detection • Microprocessor clock signal generation (see Microprocessor Clock Synthesizer Description Block).

  • Page 52: High Speed Data

    This drives a tone generator inside U0201 which generates a staircase approximation to a PL sine wave or DPL data pattern. This internal waveform is then low-pass filtered and summed with voice or data. The resulting summed waveform then appears on U0201-H8 (MOD IN), where it is sent to the RF board as previously described for transmit audio.

    The outputs of the Audio PA (EXT-SPKR+, INT/EXT SPKR-) are routed to the external speaker through the accessory connector. The INT/EXT SPKR- is directly connected to the INT-SPKR(-).
