Other Parts Discussed in Thread: TLK10034
Hi. I would like to know if exist clear line loop on High Speed interface.
I mean physical loop Rx to Tx without any other internal schematics like clock recovery etc.
Thanks,
Yuli

Hi Yuli,
The deep remote loopback is able to connect TX with RX physically. Please take a look into Figure 5-6 of TLK10034 datasheet.

Hi, Luis.
Nope. None of them is suitable for me.
Because internal schematics is involved in data path.
The problem is auto negotiation process
The HiF side is connected to device with AN.
This will operate correctly with true physical loop.
If TI PHY can be configured as shallow local loop (with HI side Tx connected to Rx) so why it cannot be connected in remote loop?

Thanks, Luis.
I see.
The purpose of this loop is to allow 1G auto neg process.
In case of deep loop back this is impossible.
Do you have any idea?
Yuli
