Abstract

Le dispositif (DV) comprend une boucle à verrouillage de phase (PLL) et une boucle à verrouillage de fréquence (FLL) ayant en commun le même oscillateur commandé (DCO). Le dispositif est mis premièrement dans le mode d’émulation de carte -CE- au début d’une communication entre ledit dispositif de communication sans contact (DV) et un lecteur sans contact (RD) et à la réception par le dispositif de communication sans contact d’une indication envoyée par le lecteur indiquant une autre communication dans un mode pair à pair avec ledit lecteur, le dispositif (DV) est mis deuxièmement dans le mode pair à pair -P2P-. Dans le mode CE on utilise les deux boucles à verrouillage ou seulement la boucle à verrouillage de phase, tandis que dans le mode P2P, la boucle à verrouillage de phase est désactivée et seule la boucle à verrouillage de fréquence est utilisée.
