Interface Mode Clocking

The on-chip PLL2 and PLL2 Controller generate all the clocks to the EMAC module. When enabled, the input clock to the PLL2 Controller (CLKIN2) must have a 25 MHz frequency. For more information, see Section 7.8, PLL2 and PLL2 Controller.

The EMAC uses SYSCLK1 of the PLL2 Controller to generate the necessary clocks for the GMII and RGMII modes. When these modes are used, the frequency of CLKIN2 must be 25 MHz. Also, divider D1 should be programmed to ÷2 mode [default] when using the GMII mode and to ÷5 mode when using the RGMII mode. Divider D1 is software programmable and, if necessary, must be programmed after device reset to ÷5 when the RGMII mode of the EMAC is used.
