Part Number: AM3351
Hi,
In section 14.2.4 of the AM335x Technical Reference Manual it states that the RMII interface reference clock pin operates as an input. I understand that this needs to be clocked by a 50MHz low-jitter source, either from a PHY or external oscillator.
In Figure 14-2, however, the RMIIx_REFCLK is shown as being either an input or an output, with the output being a 50MHz clock sourced from the PRCM.
Does this mean that the RMIIx_REFCLK pin can act as a 50MHz clock source for an external PHY ?
Best Regards
Pete Baston.
