TMS320C6711D: PLLHV current draw and filter circuit requirements

Munan Xu

Part Number: TMS320C6711D

Hello,

I have a customer with an existing C6711D based design. It looks like the Panasonic  ELK-E103A/U type LC LPF filters are going obsolete/ EOL. 

Is it acceptable to use a something like this as a replacement?

https://www.digikey.com/product-detail/en/tdk-corporation/MEM2012S25R0T001/445-6199-1-ND/2465526

Also what is the current draw going into the PLLHV pin?

Regards,

Munan

    Hi,

    Any filter that is similar to Panasonic ELK-E103A/U type LC LPF would do the trick. The only concern I have is that ELKE103A/U can take more current than the filter you linked in digikey website.

    As for the current draw going into the PLLHV pin, I suggest you check the CORE current in Recommended operating conditions table in the device datasheet.


    Best Regards,
