Hello,

 

We are developing a custom board for AD9364 with the reference of the FMCOMMS5 board for AD9361.

We have queries related to the current consumption of the 1.3v rail of AD9364 transceiver.

 

  1. We require the current consumption for individual rails of the 1.3v supplies of AD9364.
    1. VDDA1P3_RX_TX
    2. VDDA1P3_TX_VCO_LDO
    3. VDDA1P3_RX_RF
    4. VDDA1P3_RX_LO
    5. VDDA1P3_RX_VCO_LDO
    6. VDDA1P3_TX_LO_BUFFER
    7. VDD1P3_DIG
    8. VDDA1P3_RX_SYNTH
  2. Kindly let us know if there is a specific reason to split the 1.3v supply among two ADP1755 LDOs as shown in the schematic of FMCOMM card.


Thank you for your time.
