    CIRCUIT DESCRIPTIONS Introduction The SIMRAD RD68 consists of 3 PCB assemblies. The main Receiver / Transmitter PCB assembly, Navico Part No. E03866, contains all the transmitter and receiver circuitry including the synthesiser, modulator and audio power amplifiers. The control PCB assembly, Navico Part No. E03656, houses the microcontroller, user controls and interfaces, display module and ATIS detection and mute circuitry.
  • Page 24 PIN diode D103 ensuring that there is a suitably high reverse bias across it in the OFF condition. NMEA Reception. (RD68 only) Position and time information, from a GPS unit, is received in the form of NMEA data. This is opto-coupled into the radio via R225, D5 and IC4.

  • Page 26: Control Pcb Assembly

    Control PCB Assembly. Refer to drawing number E03656. All the functions of the radio are controlled from this assembly by the microprocessor IC4. The microprocessor has it own clock controlled by XTAL1 running at 7.15909MHz. Reset generator IC9 ensures that the microprocessor starts up correctly and resets under low voltage conditions.
  • Page 27 The audio level required for alarms is controlled by IC1d. For normal key ‘ beeps’ the microprocessor, IC4, generates a square wave which is filtered and reduced in level by R15, R75, C14 and C105 and then fed into the audio amplifier via PLG1.

  • Page 29: Second Receiver Pcb Assembly

    Second Receiver PCB Assembly Refer to drawing number E03209. The second receiver is connected to the main receiver at the power splitter L10, C215, C214 and R205. The basic circuitry is the same as the receiver section of the main receiver.
