Patent

CA 2372799

A system and method for programming (1-7) a digitally tunable oscillator (2) is provided. A desired output frequency is received. A tuning effect of a set of digital tuning words on a crystal (2) resonant frequency is determined (3), and valid parameters of an algorithm for translating and tuning the crystal resonant frequency to a value within an error tolerance of the desired frequency based on the determined tuning effect are calculated (4).

L'invention concerne un système et un procédé pour programmer (1-7) un oscillateur réglable numériquement (2). On reçoit une fréquence de sortie désirée. On détermine (3) un effet de réglage d'un ensemble de mots de réglage numériques sur la fréquence de résonance d'un cristal (2) et l'on calcule (4) les paramètres valides d'un algorithme pour traduire et régler la fréquence de résonance d'un cristal à une valeur comprise dans une tolérance d'erreurs de la fréquence désirée, sur la base de l'effet de réglage déterminé.
