Tool/software:
In TI's DS2x0DFx10 Ethernet retimer devices, there is a Version ID register that can be used to read back the device version. For groups implementing this device, we frequently see them checking this Version ID to confirm that the DS2x0DFx10 is correctly installed in their system and responding.
Sometimes, TI receives questions about why the Version ID is not matching expectations. The primary cause for this is that some DS2x0DFx10 devices have multiple valid Version IDs. For example, the DS280DF810 has valid Version IDs of 0x30 or 0x31.
The table below is an excerpt from the DS2x0DFxx0 Programmer's Guide. This shows valid Version IDs for multiple 25G/28G retimer devices. For the latest set of Version IDs, please reference the DS2x0DFxx0 Programmer's Guide.
