AM2634: Can the LDO generated 1.8V supply be used to power external parts?

Part Number: AM2634

Hello,

My team is using a AM2634COMFHAZCZR, we can see there is a 1.8V LDO Supply for the analog modules, and we are wondering if we can use this supply to power an external oscillator.

    Hi Karla,

    It is not possible to use the 1.8V LDO supplies for any external components. The supplies are designed specifically to power the various 1.8V rails inside of the IC and nothing more so it cannot support any external loads being added.

    This is unfortunately a gap in our documentation so we will look to add some verbiage regarding this to one or both of our datasheet and hardware design guide.

    Best Regards,
