How can I change the ULPI CLK for TUSB1310AZAYR PHY?

Other Parts Discussed in Thread: TUSB1310A

Hello,

We got the ULPI_CLK incorrect problem, we should get the default value (60MHz) in this output pin (from datasheet),

but 75MHz is the measuremed value we got. Please kindly support us: how to revise this CLK value from 75MHz to 60MHz?

Here is our inital HW latch :  (Is there anything we lose?)

REFCLKSEL0: 1 , REFCLKSEL1: 0  ,   ISO_START: 0   ,    SSC_DIS:  0  ,    PHYMODE0:  1 ,      PHYMODE1:  0 

Thanks a lot.
