Abstract[English]
Disclosed is an impedance calibration control circuit, comprising a calibration control circuit, which is configured to output a first calibration code; a logic conversion circuit, which is configured to receive the first calibration code and a second calibration code, and output a third calibration code after performing calculation on the first calibration code and the second calibration code; and a plurality of calibrated units, which are configured to receive the third calibration code, and perform impedance adjustment on the basis of the third calibration code.[French]
Est divulgué un circuit de commande d'étalonnage d'impédance, comprenant un circuit de commande d'étalonnage, qui est configuré pour délivrer en sortie un premier code d'étalonnage ; un circuit de conversion logique, qui est configuré pour recevoir le premier code d'étalonnage et un second code d'étalonnage, et délivrer en sortie un troisième code d'étalonnage après réalisation d'un calcul sur le premier code d'étalonnage et le second code d'étalonnage ; et une pluralité d'unités étalonnées, qui sont configurées pour recevoir le troisième code d'étalonnage, et réaliser un réglage d'impédance sur la base du troisième code d'étalonnage.[Chinese]
