Electronic system for clock resynchronisation

Abstract

Abstract The system (1) comprises an internal clock (7), supplying a signal of imprecise period T1, and clock resynchronisation means configured to determine (8) the number N of periods T1 of the signal of the internal clock (7) during which the signal of the internal clock (7) has experienced a drift of a period To with respect to the reference signal with period To of an external clock (3), and in order to supply (12) a signal, of period NT1, of pulses intended to delay the signal of the internal clock (7) by a duration PTo, P being a whole number equal to or greater than 1. The invention is well suited to a portable radiotelephony terminal. <IMAGE>
