Bidirectional communication system and calibrator
View Patent ↗A master station includes a group of circuits for performing an optimization method. In such a system, the optimization is achieved by adjusting the pull-up resistance and by setting the best possible clock frequency to ensure that data/clock high and low voltage levels are within predetermined specifications. An optimization procedure is performed in a calibration phase invoked by a user or a system whenever a change is introduced to the system, such as addition or deletion of slave stations, a change of data/clock lines, or a change that may affect on the electrical and timing characteristics of the two-wire communication system.
1. A calibrator connected to a clock supply station, comprising:
a processor; and
a clock control block and a peak detector connected to the processor,
wherein said processor controls said clock control block according to a peak voltage detected by said peak detector, and controls a clock frequency supplied by said clock supply station.
2. The calibrator according to claim 1 ,
wherein said processor controls said clock control block so that said peak voltage is a target peak voltage.
