I am trying to use ADuM1402 As UART isolation. I have created schematic as following. Is it correct or any modification is required. Same way I have created ADN4650 schematic can someone verify and let me know if it is ok?

I am trying to use ADuM1402 As UART isolation. I have created schematic as following. Is it correct or any modification is required. Same way I have created ADN4650 schematic can someone verify and let me know if it is ok?

The UART is working at 19200 baud rate.

Following Circuit shows LVDS signals used for driving display signals. I have connected total 3 ADN4650 IC. there are 4 Differential signal channels and one clock channel.

Following IC shows the Circuit for Clock signal. other Signals are also connected in similar configuration

  • Hi,

    Thanks for your query.

    Your ADuM1402 schematic looks fine. If you'd like me to review the pcb layout in relation to the ADuM1402 then please feel free to contact me via email.

    Just a note the C101, &C99 1uF caps may not be needed if these are for ADuM1402 IC bypass caps. If this is for board power supply decoupling or similar then please ignore this note.

    Best Regards,

    Shane
