Part Number: TMS320C6678
Hi,
I see that on the 6678 EVB, 312.5Mhz is used as SGMII clk.
I would like to use 250Mhz in a new design,
HW changes: Bootconfig bits 9-8 SerDes Clock Mult need to change to '01' instead of '10'.
Q: Do I also need to change the Kernel? SGMII_SERDES_CGFPLL(MPY) ?
Q: Any other changes?
Q: Can you confirm 250Mhz was tested\used and works OK?
Q: Is the 312.5Mhz preferred in any way?
Regards,
Amir
