|
|
For RGMII, "output" is recommended, means main clock(125MHz)
|
|
is sourced from SoC's PLL, use output can get better electrical
|
|
signal; and "input" is not sourced from SoC's PLL, but input from PHY.
|
|
For RMII, "input" means PHY provides the reference clock(50MHz),
|
|
"output" means GMAC provides the reference clock.
