DP83822HF: RGMII mode - connexion HW from PHY to MAC

Part Number: DP83822HF

Hi Experts,

In RGMII mode, the pin RX data (x6) have to be 50 Ohm impedance.

In the datasheet, we did not find the paragraph that explains the presence of the internal impedance (50Ohm). 

Question: Is there an existing internal 50ohm impedance? 

 

In next schematics, I explain my question : 

Please help confirm. Thank you.

Best regards,
Gerald
