LMK04828: LMk04828

Part Number: LMK04828

The LMK04828 in our system is configured as"

DCLKout8 at 250Mhz, SDCLKout9 at 6.25Mhz as SYSREF.

DCLKout10 at 250Mhz, SDCLKout11 at 6.25Mhz as SYSREF.

After programming the LMK to the above configuration and the system is running. We need to change DCLKout10 to 150Mhz. (VCO is 3000Mhz)

So write to registers 0x128-0x12F with 0x128 change from 0x0C to 0x14, the reset is the same. 

We have an ILA that monitors the SYSREF. the SYSREF frequency changed after change the register 0x0128-0x12F. 

Does the SYSREF needs to be reset and how?
