Anotation

This guide addresses some of the special problems encountered in specifying and using quartz crystal units for frequency control with the integrated circuit oscillators commonly incorporated on microprocessor silicon devices. The special problems include the (usually unspecified) phase delay and parasitic parameters of the active circuits which often result in unpredictable behaviour of the oscillator circuit. Traite de certains problemes speciaux rencontres lorsquon specifie et utilise des resonateurs a quartz pour la commande de la frequence avec des circuits oscillateurs integres habituellement incorpores dans les dispositifs au silicium des microprocesseurs. Ces problemes speciaux comprennent le retard de phase (habituellement non specifie) et les parametres parasites des dispositifs actifs qui resultent souvent du comportement imprevisible du circuit doscillateur.
