Part Number: LM48310

Hi,

For the LM48310 part, could I connect the VDD to 3.3V and PVDD to 5V separately? Thanks.

Hi Hai,

All the documentation of LM48310 is specified for a short between VDD and PVDD, so implementing the device in a different way may not follow the specified performance.
I'm not sure what would be the reason to use two different supplies, but I would recommend following the recommendation and short these pins together.

Best regards,
