Hello,
I am working on the Hardware design part of Texas Instruments DP83620 Ethernet Phy
This IC provides a common output TX+/- and RX+/- for both Copper and Fiber mode and there are some strapping options of adding and removing the resistors to configure the IC in either modes.
My application requires both these modes to be designed on the PCB and should be field configurable. Now based on the evaluation kit it contains a set of 0 ohms resistor which can be stuffed or removed to use either of Copper or fiber mode however this cannot be done in the fields once the product is designed.
One way is using a Jumper or switch to achieve this where I am skeptical about the performance since this is a high speed part they signals are bound to get disturbed with these solution.
I am looking for an efficient solution which could be field configurable.
Thank you.
