KEYSTONE - Marvell mdc/mdio clock configuration

Hello Forum Members ,

We are trying to configure to configure Ethernet External switch from 66Ak2h keystone processor.

According to data sheet

3.4.2 MDIO Control Register (MDIO_CONTROL)->
Register 15-0 CLKDIV Clock Divider.
MDCLK frequency = peripheral clock frequency/(CLKDIV+1).

MDCLk required Frequency lies in (1 Mhz -2.5 Mhz).


The doubt is "peripheral clock frequency" mentioned is the System clock supplied from PLL,presently which we are using is 1ghz.

Is my assumption true..?

Thanks in advance.

Regards,

Krishnan
