IWR1443BOOST: If NO PMIC_CLKIN signal and this pin is not grounded, does it impact the performance

Part Number: IWR1443BOOST

In IWR1443Boost schematic, there is no PMIC_CLKIN signal since the resistor R97 is not installed, the PMIC_CLKIN pin also is not grounded as required from PMIC data sheet, does this impact the performance of PMIC?

Thanks!

    Hello,

    Related to the PMIC using an internal clock (since we are not driving the PMIC_External clock, If the PMIC datasheet (which was released after the EVM) indicates the pin should be pulled to GND,  I would follow the PMIC data sheet.   I have not experienced a PMIC not starting using the 1443 or 1642 EVMs.
