4 Clock Distribution - MAC Interface Clocking

After power-up the PHYs are configured to implement parallel RMII MAC interfaces.

PHY1 is configured in RMII master mode and is responsible to generate all necessary clocks
for the 2nd PHY (PHY2) as well as the MAC interfaces. PHY1 needs a 25MHz clock reference
on its X1 clock input, which must be provided by the application through the HSMC connector.

The MAC interface is synchronous to the 50MHz reference clock provided by PHY1. PHY1
provides the RMII interface clock on its

rx_clk

and

tx_clk

outputs.

The PHYs are configured (see Strap Options, see section 5.2) to provide the internal
synchronized IEEE 1588 clock on its

clk_out

pin, which is available to the HSMC for use by

1588 related functions of the application.
