VAR-SOM-AM62 rev changelog

VAR-SOM-AM62 changelog

VAR-SOM-AM62 (February 2024)

Hardware Modifications

Removal of RGMII TX CLK delay filters on both Ethernet interfaces.

The RGMII spec requires a skew between the clock and data at the receiver. On previous assemblies, the delay was introduced on the SoM via an inline filter
