Other Parts Discussed in Thread: TUSB9261DEMO, TUSB9261, TUSB7320, TUSB7340

Hello. We are Disty of Japan area.
Our Customer have question about TUSB9261DEMO.
I think that Positive/Negative of REFCLK wiring(to slot connector) is reverse.
Is 「TUSB9261 DEMO User's Guide」writing error ?
(P.14-P.15 and  P.18-P.19)
Signal label is 『 PCIE_REFCLKP 』　and　『 PCIE_REFCLKN 』.
And please give me BOM List of TUSB9261DEMO.

    Hello Ryuji,

        Maybe your customer is referring to the TUSB73x0, because the TUSB9261 is a bridge between USB3 and SATA and both signals; PCIE_REFCLKP/N belongs to the PCIe interface, which also appear in the mentioned pages (14,15,18 and 19 of the TUSB7320/TUSB7340 EVM User's Guide http://www.ti.com/lit/ug/sllu146b/sllu146b.pdf ).

        Now; assuming that You are talking about the PCIE_REFCLKP/N signals, this is not a writing error since those signals are a differential clock and can be swapped.

    Best regards,

    Diego.
