    Chapter 2 Circuit Description FAX-30 consists of MAIN, RCV and I/F boards. 2.6 m whip antenna + FAX-5, wire antenna or 6 m whip Power supply 12 VDC to 24 VDC NAVNET or PC M connector POWER LED MJ3P connector...
  • Page 11 MAIN board (08P3218) MAIN board consists of CPU, NET and PWR circuits. CPU circuit CPU consists of 32-bit CPU&DSP with a built-in Ethernet controller, 24-bit CODEC (AD converter), Flash ROM and SDRAM. The main function of CPU&DSP (U18) is as follows. 1) Filtering of received signal (DSP) 2) Demodulation of FAX data (DSP) 3) Demodulation of NAVTEX data (DSP)
  • Page 12 NET circuit Net circuit is Ethernet 10Base-T interface circuit using TCP/IP protocol. U2 is a full feature Physical Layer device with integrated PMD (Physical Medium Dependant) sublayers to support 10Base-T Ethernet protocol. PWR circuit Fig.4 shows the block diagram of power supply circuit. The power supply circuit employs a floating type flyback switching regulator.

  • Page 14 RCV board (08P3219) Three bandpass filters, FL1, FL2 and FL3 locate at the first stage of the receiver. The filter passes the following frequencies. When receiving NAVTEX message, FL3 is used. FL1: 2 MHz to 13.2 MHz FL2: 13.2 MHz to 25 MHz FL3: 80 kHz to 518 kHz The shift register, U10 receives three signals, RCV DATA, RCV CLK and RCV BAND from MAIN board to select the filter.
  • Page 15 The synthesizer consists of 18 MHz oscillator, Direct Digital Synthesizer (DDS), PLL and VCO. The signals from MAIN board, RCV DATA, RCV CLK, RCV DDS, RCV PLL and RCV BAND, determines the frequency of the local oscillator depending on the selected receiving frequency. When the synthesizer unlocks, RCV UNLOCK signal is generated for the error message.
