TMS320C6657: Reference clock (DDRCLKP/DDRCLKN) when DDR3 is not used

KENGO AKIKAWA

Part Number: TMS320C6657

Tool/software:

Is a reference clock (DDRCLKP/DDRCLKN) necessary even if the DDR3 interface is not used?

(DDR3 device is not implemented)

I did not understand the content of "Even if the DDR3 interface is unused, a reference clock is still required to ensure that the DDR peripheral is initialized to a proper state." in the document "Hardware design guide for KeyStone I devices".

KENGO AKIKAWA,

If the "Hardware design guide for KeyStone I devices", says that the reference clock is required, it is better to follow them. ( May be the design is done that way )
