Hi, 

 

When using ENET, there is a description in i.MX 6DQ data sheet below. Is it possible to reduce clock accuracy 50ppm to 100ppm when it use MII mode instead of RMII mode?

 

4.11.5.2 RMII Mode Timing
In RMII mode, ENET_CLK is used as the REF_CLK, which is a 50 MHz ± 50 ppm continuous reference clock.

 

Best Regards,

Sugiyama
