SGMII/RGMII internal clocking possible

Is internal clock generation for RGMII/SGMII possible or is external clock device required?

Hi Thorsten,

Please see the Serdes diagrams in J7. They are applicable to all four 2-lane Serdeses in any mode.

PCIe 100-MHz clock can be internally or externally generated, similarly to earlier SoCs. For SGMII, PLL clock can be generated internally.

Regards,

Stan
