CIRCUIT DEVICE, ELECTRONIC DEVICE, COMMUNICATION SYSTEM, AND VEHICULAR ELECTRONIC KEY SYSTEM
To provide a circuit device or the like that can prevent occurrence of problems caused by an error in synchronization of clock signals in a communication system in which devices communicate with each other.SOLUTION: A circuit device 10 is used in an electronic device 90 including: a receiver 70; a control circuit 60 that performs a process by using a clock signal CLK on reception data DR received by the receiver 70; and a transmitter 80 that transmits transmission data DT generated as a result of the control circuit 60 performing a process on the basis of the reception data DR. The circuit device 10 includes a time-to-digital converter circuit 20 that measures a time difference between a transition timing of a start signal STA based on the reception data DR and a transition timing of a stop signal STP based on the transmission data DT or the clock signal CLK, and an output interface 30 that outputs a measurement result MQ of the time difference measured by the time-to-digital converter circuit 20 to the control circuit 60.SELECTED DRAWING: Figure 1
【課題】機器間で通信を行う通信システムにおけるクロック信号の同期誤差を原因とする問題の発生を防止できる回路装置等の提供。【解決手段】回路装置１０は、受信機７０と、受信機７０が受信した受信データＤＲに対してクロック信号ＣＬＫを用いて処理を行う制御回路６０と、制御回路６０が受信データＤＲに基づいて処理を行うことで生成された送信データＤＴを送信する送信機８０と、を含む電子機器９０に用いられる。回路装置１０は、受信データＤＲに基づくスタート信号ＳＴＡの遷移タイミングと、送信データＤＴ又はクロック信号ＣＬＫに基づくストップ信号ＳＴＰの遷移タイミングとの時間差を測定する時間デジタル変換回路２０と、時間デジタル変換回路２０の時間差の測定結果ＭＱを制御回路６０に出力する出力インターフェース３０を含む。【選択図】図１
