Večkanalni programabilni frekvenčni sintetizator kot nadomestek kristalnih oscilatorjev

diplomsko delo

Janko Koležnik (Author), Boštjan Vlaovič (Mentor)

Abstract

V diplomskem delu je opisano načrtovanje in izdelava miniaturnega nadomestka kristalnim oscilatorjem s konstantno frekvenco, z dodano možnostjo izbire delovne frekvence. Cilj naloge je bila izdelava oscilatorja s spremenljivo frekvenco, modula za upravljanje oscilatorja, komunikacije med modulom in osebnim računalnikom ter programa za izračune na osebnem računalniku. Za oscilator smo v napravi uporabili vezje Si5351A podjetja Silicon Labs, za upravni modul pa mikrokrmilnik ATtiny45 podjetja Atmel. V delu je opisan potek od začetne zamisli do izvedbe dveh prototipov, opis uporabljene programske kode ter opis izvedbe končnega izdelka.

Secondary title:	MULTI-CHANNEL PROGRAMMABLE FREQUENCY SYNTHESIZER AS A SUBSTITUTE FOR CRYSTAL OSCILLATORS
Secondary abstract:	This diploma thesis presents the design and the construction of the miniature fixed frequency crystall oscillator replacement with additional feature allowing setting of the operational frequency. The aim of the diploma thesis was the construction of the variable frequency oscillator, control module for the oscillator, communication between module and personal computer and development of the software for calculations on the personal computer. As oscillator we used integrated circuit Si5351A from manufacturer Silicon Labs and microcontroller ATtiny45 from Atmel Corporation as the control module. Diploma thesis describes path from initial idea to construction of two prototypes, implementation of the software and construction of the final product.
