Spread Spectrum Clock for Ethernet

Question asked by on Apr 29, 2020

Our platform based on I.MX6ull (Variscite DART 6ULL) with enabled 1 Ethernet port (of 2).

We would like to certificate our product, but we have got an EMC Ethernet issue.

During EMC tests we have observed 50MHz peak and its harmonics.

The disruption disappear when Ethernet went down (ifconfig eth0 down).


Is it possible to enable spread clock to Ethernet?
