Hi,
We are using the ISO7841 for SPI communication isolation with external sensors. The SPI speed is 4Mhz.
The traces from the MCU to the isolator and from the isolator to the sensor (connector and electronics) are intact
We have a problem that the signal that is coming from the MCU ( SPI - SCL and MOSI ) can not be seen on the other side of the isolator. On the other side only 3V can be seen everitime.
What can be giving this problem ?
Regards,
Robert
