DP83826E: Alternate clocking from MCU

Part Number: DP83826E


Hello TI experts, 

Please see attached image. Figure 9-5 from DP83826E datasheet shows 50Mhz reference clock to be given by a common clock source to both MAC and PHY. 

As shown on the right hand side, is it OK to clock DP83826E with 50Mhz clock from HOST MCU MAC? 

Thanks.
