SN65DPHY440SS: The power supply to the MIPI Re-timer is experiencing a dip in the voltage.

Sushmitha S

Part Number: SN65DPHY440SS

We have connected the MIPI Re-timer between the camera and the Processor. Randomly the power supply to the MIPI re-timer is experiencing a dip in the voltage which is supplied by the module itself. Because of this we are experiencing problems in streaming the camera. The current rating of the Switcher used to power the MIPI re-timer is around 300mA . kindly provide a solution to this issue as soon as possible.

Do you have ferrite bead on power supply? what caused dip? by device itself?

Yes we have a ferrite bead in our supply. We are not sure about the voltage dip. Usually the MIPI Retimer consumes around 85mA. But the re-timer is consuming around 120mA randomly. Even with the external power supply we are facing an issue with the current consumption. Please provide a solution for the same.

Sushmitha:

We need to find out if the dip caused by over current or switching noise from power supply.
