Title (EN) LARGE SUPPLY RANGE DIFFERENTIAL LINE DRIVER
(FR) CIRCUIT DE COMMANDE DE LIGNE DIFFERENTIEL A PUISSANTE ALIMENTATION
Abstract: front page image
(EN)A differential transmission line driver with supplemental current sources (N3, N4; P3, P4) that overcome switching anomalies and EM issues when the logic state of the driver is switching. During a logic transition, a current source (Pl, P2; Nl, N2) , that is directed to the output (out P, out M) of the driver, may be prevented from delivering its current. The present invention provides a supplemental current that is active during this transition period to supply the missing current. The present disclosure also details a common mode circuit that maintains a stable common mode output level to help control EMI issues when the power supply for the driver changes .
(FR)L'invention concerne un circuit de commande de ligne de transmission différentiel comprenant des sources de courant différentielles (N3, N4; P3, P4) permettant de régler les anomalies de commutation et les problèmes d'interférences électromagnétiques lorsque l'état logique du circuit de commande est commuté. Au cours d'une transition logique, on peut empêcher une source de courant (Pl, P2; Nl, N2), dirigée vers la sortie (sortie P, sortie M) du circuit, de distribuer le courant correspondant. La présente invention permet d'obtenir un courant supplémentaire actif au cours de cette période de transition pour fournir le courant manquant. La présente invention concerne également un circuit en mode commun maintenant un niveau de sortie en mode commun stable afin de régler les problèmes d'interférences électromagnétiques lorsque l'alimentation du circuit de commande change.
