Differential clock enable for HyperRAM inerface in STM32N657

[kadam]

Hello Team,

We have developed custom board using STM32N657. We are using HyperRAM P/N: S80KS5122GABHI023 in our design.

We are configuring HyperRAM at clock frequency 100MHz in DDR mode. When we measure clock on PO5 port, Inverted clock is not available but on PO4 port clock is available.

Could you guide us for register setting to get differential clock on both PO4 and PO5 ?

Below is schematic for reference

 

Your quick response is highly appreciated.

Thanks
