PROGRAMMED CLIP DECODER (FSK) - PRINTED BOARD AND PROGRAMMED LAYOUT

Producer: AVT

The number sharing service is standard in cellular networks and the ISDN system. Analog subscribers can use it provided they are connected to a digital exchange. On the recipient's side, the CLIP FSK decoder is still required. You can do it yourself by installing the AVT590 kit. The use of a simple, properly programmed microcontroller eliminated the need for a hardware decoder. Thanks to this, it was possible to significantly reduce the cost of the device and abandon the use of specialized integrated circuits. The system is simple to make and run and at the same time reliable.

The device is especially recommended for phone users, who want to avoid unwanted calls and also those who like to know who is on the other side of the 'line'

Selected decoder parameters:

  • reading subscriber's number, current date and time
  • AT90S2313 microprocessor
  • V.23 protocol
  • work with CLIP waveforms with amplitude 100-560 mV
  • read - 16x2 alphanumeric LCD display
  • power supply - 15-20 V
  • a printed circuit board, programmed layout and documentation in the set
    A version with a set of components for self-assembly is available
