Other Parts Discussed in Thread: DS160PT801
Hi TI team,
Test Target:
PCIe device SI test with TI DS160PT801X16EVM PCIe riser card board.
Compliance load (base) board sends a 100 MHz signal for about 1 ms to PCIe device’s receiver, to cycle the PCIe device to the desired link speed and de-emphasis level.
Test Question:
With TI DS160PT801X16EVM PCIe riser card board, How to makes PCIe device under test link speed and de-emphasis level can cycle among “Gen1 -3.5db -> Gen2 -3.5db -> Gen2 -6db -> Gen3 preset0 -> Gen3 preset1 -> ……..Gen3 preset10 -> Gen1 -3.5db”???
Current test result:
1). With TI DS160PT801X16EVM PCIe riser card board, the PCIe device under test link speed and de-emphasis level can NOT change. It is a unexpected result.
2). Without TI DS160PT801X16EVM PCIe riser card board, the PCIe device under test can cycle among “Gen1 -3.5db -> Gen2 -3.5db -> Gen2 -6db -> Gen3 preset0 -> Gen3 preset1 -> ……..Gen3 preset10 -> Gen1 -3.5db”, it is a expected result.
