Tool/software: Interface Forum

Hi all,

On top of the above link, I Cant able to communicate Ds90UB933 Serializer from DS90UB934 Deserializer.

In 934 Deserializer, I read the Address: 0x04 (Status Register), The Value i am getting here is : 0xc0

this means, LOCK not happened between serializer and Deserializer and its not passed also.

In our board, we are not using any IO Expander for FPD Communication as like D3/EVM. I muxed GPIO to control all pins.

The steps i followed in pinmux for FPD Initialization :

  • Set PDB bits high for all FPD Link channels
  • Set Lock and Pass bits high for Driver cam FPD Link channels
  • Set OE bits high for all FPD Link channels

How to Enable VDD_FPD Sepic A, B - EN ? ( We are not using Sepic) ?

How to Enable VDD_FPD Sepic Enable output power FPDA & B SW EN  ?

How to LOCK the SER-DESER to communicate via FPD STP (Shielded Twisted Pair) Cable ?

Can anyone help me, regarding the above issue. Its little-bit emergency.

Regards,

  • This is the processor forum. Suggest you to post SerDes related issues on FPD Link support forum.
