    Abstract: A data communication system comprises a transmitting device which transmits data and a receiving device which receives the data. The transmitting device comprises a clock generating circuit and a transmitting unit. The clock generating circuit generates a clock having a temperature characteristic in that a clock frequency varies with temperature. The transmitting unit transmits data generated in synchronization with the clock to the receiving device. The receiving device comprises a receiving unit, a detecting unit, a storage unit, and a calculating unit. The receiving unit receives the data. The detecting unit detects the clock frequency from the data. The storage unit stores temperature characteristic information regarding the temperature characteristic of the clock frequency. The calculating unit calculates a temperature corresponding to the clock frequency based on the clock frequency and the temperature characteristic information.

    Abstract: PROBLEM TO BE SOLVED: To solve such a problem that an information processing apparatus for an external device controller etc., may fail to detect whether there is a delay with conventional constitution when data received from an external device are one or more cycles delayed behind an output clock of the external device controller. SOLUTION: When adjusting a data input timing of the external device controller, the information processing apparatus improves precision of calibration for adjusting the data input timing by gating or canceling the output clock of the external device controller on the basis of prescribed gating information.

    Abstract: ロジックブロック103では、クロック生成部104において生成したクロック信号CLKを用いてシリアルデータ信号DATAを生成する。その後、スキュー調整部111では、前記クロック信号CLKと前記シリアルデータ信号DATAとの位相関係に基づいて、前記シリアルデータDATAの遅延を調整して、遅延を調整したシリアルデータ信号DATA−SK及び前記クロック信号CLKをFF回路112に出力する。前記FF回路112では、クロック信号CLKを用いて、前記シリアルデータ信号DATA−SKを整形して、その整形後のシリアルデータ信号DATA−FFを外部に伝送する。従って、信号処理したデータ信号にクロック信号のジッタが重畳されている場合であっても、そのジッタの影響を低減して外部にデータ信号を伝送可能なデータ送信装置を提供することが可能となる。
