Abstract
(EN)
A multilevel-signal transmission device (100) transmits a multilevel data signal having a number of voltages equal to M, which is an even number that is 4 or higher, and a multilevel clock signal having M-2 voltage levels, to a multilevel-signal reception device (200). The multilevel-data-signal voltage levels include M/2 first voltage levels which are larger than a reference voltage level, and M/2 second voltage levels which are smaller than the reference voltage level. One of the multilevel-clock-signal voltage levels is positioned between each pair of mutually adjacent multilevel-data-signal first voltage levels, and one of the multilevel-clock-signal voltage levels is positioned between each pair of mutually adjacent multilevel-data-signal second voltage levels. The average value of the multilevel-clock-signal voltage levels is a value between the minimum value among the multilevel-data-signal first voltage levels and the maximum value among the multilevel-data-signal second voltage levels.

Selon l'invention, un dispositif d'envoi de signal multi-niveau (100) envoie un signal de données multi-niveau ayant un nombre de tensions égal à M, qui est un nombre pair valant 4 ou plus, et un signal d'horloge multi-niveau ayant M-2 niveaux de tension, à un dispositif de réception de signal multi-niveau (200). Les niveaux de tension de signal de données multi-niveau comprennent M/2 premiers niveaux de tension qui sont supérieurs à un niveau de tension de référence et M/2 seconds niveaux de tension qui sont inférieurs au niveau de tension de référence. Un des niveaux de tension de signal d'horloge multi-niveau est positionné entre chaque paire de premiers niveaux de tension de signal de données multi-niveau mutuellement adjacents, et un des niveaux de tension de signal d'horloge multi-niveau est positionné entre chaque paire de seconds niveaux de tension de signal de données multi-niveau mutuellement adjacents. La valeur moyenne des niveaux de tension de signal d'horloge multi-niveau est une valeur comprise entre la valeur minimale des premiers niveaux de tension de signal de données multi-niveau et la valeur maximale des seconds niveaux de tension de signal de données multi-niveau.
