Abstract
In this paper, a new pure-digital frequency synthesizer Fout =(X/Y)∙Fin for square-waves with controlled precision is described. Given that Fin is the input reference frequency provided by a stable crystal oscillator, Fout is the synthesized frequency; X and Y are two co-prime integer numbers.
The purpose is to demonstrate that with exclusively simple digital techniques, a frequency synthesizer with high precision, fast switching time and medium frequency bandwidth can be achieved.
In conformity with design-reuse methodology, the frequency synthesizer is implemented as technology-independent and generic IP-core, easily adaptable to suit any particular need.
