Other Parts Discussed in Thread: TUSB7320

Hi Champs,

According to a TUSB73x0 U/G below, there are electrical specifications for PCIe RefClk (PCIE_REFCLKP/N) in the TUSB73x0 Data Manual. But I could not find them in it.

So, I'd like to make sure where I can get the TUSB73x0 PCIe RefClk electrical specifications.

o TUSB73x0 Board Design and Layout Guidelines U/G [SLLU149D May14]
    (www.ti.com/.../sllu149)

    - Page 27

      8.3 PCI-Express Reference Clock Input

        ...Electrical specifications for these differential inputs are included
        in the TUSB73x0 Data Manual.

Thank you in advance for your cooperation.

Best regards,

Hello,

The absolute maximum raitings for Refclk are listed on the datasheet section 6.1. Please see the PCIe gen2 specification for a detailed information of the Refclk electrical characteristics, since the TUSB7320 is fully compliant with this spec.

Regards,
Diego.

Hi Diego,

Thank you for your information and I'd like to make sure one more thing.
What is the input buffer type of TUSB7320 PCIE_REFCLKP/N pins, LVDS, CML or anything else?

I'd appreciate if you could give me the information.

Best regards,

Hi Diego,

I don't have the PCIe gen2 specification. So, could you please let me know the input buffer type?
I'd appreciate your cooperation.

Best regards,
