Abstract
(EN) A transmission line interface circuit includes a voltage regulator to control a voltage swing of the transmission line interface circuit for signal transmission. The transmission line interface circuit includes complementary driver elements, including a p-type driver element to pull up the transmission line in response to a logic high, and an n-type driver element to pull down the transmission line in response to a logic low. The voltage regulator is coupled between one of the driver elements and a respective voltage reference to reduce a voltage swing of the transmission line interface circuit.
(FR) L'invention concerne un circuit d'interface de ligne de transmission qui comprend un régulateur de tension pour commander une excursion de tension du circuit d'interface de ligne de transmission pour la transmission de signaux. Le circuit d'interface de ligne de transmission comprend des éléments de commande complémentaires, comprenant un élément de commande de type p pour tirer vers le haut la ligne de transmission en réponse à un niveau logique haut, et un élément de commande de type n pour de tirer vers le bas la ligne de transmission en réponse à un niveau logique bas. Le régulateur de tension est couplé entre l'un des éléments de commande et une tension de référence correspondante pour réduire une excursion de tension du circuit d'interface de ligne de transmission.
