For the ADRV9029 , do the power pins VJSYN_1P0, VDES_1P0,VTT_DES and VSER_1P0 need power supply?

Category: Hardware
Product Number: ADRV9026 ADRV9029

Hi, ADI teams,

   I am so sorry to bother you, but now i really need your help.

   I got an EVAL-ADRV9026/ADRV9029 and now i am very confused about the power pins  VJSYN_1P0, VDES_1P0,VTT_DES and  VSER_1P0. My question is ,do these power pins need power supply?

    According the datasheet, it looks like these pins need power supply(1.0v).

 But according to the schamatics of  EVAL-ADRV9026/ADRV9029 and  ADP5056_PWR_BOARD and the eralier reply, these power pins(VJSYN_1P0, VDES_1P0,VTT_DES and  VSER_1P0) have no power supply.

Thanks a lot!

    You dont need to drive these supplies externally and through the Power board that gets attached to the EVB on SFMC connector should drive the supplies through the Pin, 1P0V_JESD
