When ORx selection is SPI mode, can DPD work on all 4 ports?

Category: Software
Product Number: ADRV9029
Software Version: SW6.2.0.35

I am testing DPD after selecting with ADI_ADRV9025_ORX_EN_SPI_MODE.

If DPD is enabled on only one port, DPD is performed.

However, when DPD is enabled for Port1 (Tx1, ORx1) and Port3 (Tx3, Orx3) sequentially, only Port3 that has been controlled last operates DPD.

Can both Port1 and Port3 run DPD in SPI Mode?

Or does multiport DPD only work in pin control mode?

Please help.

thank you

  • Whats your TX to ORX mapping, is it One to One?

    How you are controlling?

    If TX1 is connected to ORX1, TX2 to ORX2, TX3 to ORX3 and TX4 to ORX4 and if ORX_CTRL_A is low, the DPD will run on all the 4 channels and when to run the DPD is decided by ARM inside the chip.
