    Hello,

    Timing guidelines are located in section 7.10 in datasheet. Please note that depending on configuration, PHY may have internal delay for RGMII which user may need to account for.

    For the figure, the nomenclature may be inaccurate as the figure for 7-6 should only have R suffixes to denote the receiver, while T suffix denotes the transmitter.

    Sincerely,

    Gerome
