For a better EMC peformance we wanted to change to the CAN Transceiver SN65HVD1050. But a start up test at about -25C showed that the CAN Transceiver works sometimes with a delay of up to 800ms. That means during this time our product is not able to receive or transmit any CAN message. If we change to the CAN Tranceiver SN65HVD251 the problem does not exsist. The S port for silent mode is always low. We power the CAN transceiver with 5V and a fast settling time. At room temperature the CAN Tranceiver works as expected. Is this a known problem or is there a workaround for this issue?
