DP83826EVM: DP83826EVM: How to setting for RMII Slave Mode Test.

Hi Michael,

Unfortunately, we do not have a test guide for this.

We recommend keeping the data and clock lines length matched and the wires should be as short as possible.

Kind Regards,

Joe

Hi Joe,

Thanks for your reply.

Our customer really want to see test result data (ex, oscilloscope waveform about delay time) before and after setting RMII TX Clock Shift

I received data that is the max delay 14ns for RMII TX Clock Shift from Adrian Kam.

It is very important to select our device from customer.

So I have to provide it to our customer.

Could you please send tested data to me?

I'm looking forward to receiving good data.

BR,

Michael 

Hi Michael,

Did you mean 4ns? 

I will see if we have this data and I hope to get back to you by the end of business Friday. 

Kind Regards,

Joe

Hi Michael,

I have reached out to our validation team to see if we have this information for you. I pinged them again and I will update you as soon as I can.

Hi Michael, 

The additional 4ns was confirmed by validation but we do not have this data available to share. 

We also recommend not to use wire jumpers. 50 MHz clock over jumper wires will run your customer into signal integrity issues and setting bit will not help

Kind Regards,

Joe
