Hello,
In client products, the PHYs are located on the same board.
This means that the PHYs communicate with each other without using twisted pair cables.
Is there any problem in this case?
Also, in this case, please let us know if there are any points to note regarding pattern wiring (characteristic impedance, etc.), resistors, etc. (termination, pull-up, etc.).
An image of the component configuration is shown below.
Communication module including MAC ----- PHY (DP83826I) ----- Pattern wiring ----- PHY (DP83826I) ----- Embedded microcontroller including MAC
Best regards,
