TCAN4550:クロックが時々停止する

YUTARO ENDO
Prodigy 10 points
Part Number: TCAN4550

通信中にTCAN4550RGYRQ1のクロックが時々停止します。
対処方法をご教示下さい。
Vioには5Vを供給し、発振子は日本電波工業製の40MHzでコンデンサは日本電波工業にマッチングしてもらった2pFを使用しています。
RfとRdは取り付けていません。
コンデンサを8pFにすると頻度は少なくなりますが停止します。

    Endo-san,

    Please see this application note for deeper explanation of the oscillator circuit on TCAN4550-Q1 when using a crystal. I've also assigned an expert to address this question, but in general you'll likely have to increase the load capacitance of the crystal to stop this from occurring.

    Regards,
