PCIe external reference clock (100 MHz)

Other Parts Discussed in Thread: XIO2000A, XIO3130

Hello!

I'm doing signal integrity simulations for project where we are going to connect two boards by cable, and I'm doing simulations of PCIe gen 1 over cable.
I need model of external reference clock for PCIe, that is 100 MHz, low voltage swing differential clock, the nominal single-ended swing for each clock is 0 to 0.7V.
Could you please tell me if TI has such IBIS model?

Best regards, Marko

Hello Marko,

We only provide IBIS model of TI's devices.

We don't have what you are looking for.

Hello Elias!

I'm using TI's XIO2000A as receiver chip. Doesn't some of many TI's IBIS models, have any LVDS differential clock (CLK+, CLK-) that runs with 100MHz?

Best regards, Marko

Hello Marko,

Knowing which device you are using is much better.

You can find the IBIS model for the XIO2000A in the below link.

Hello Elias!

Yes I know, I'm already using that IBIS model for XIO200A.

I want to know if there any IBIS model for external clock that is made by TI, that has as output two signals that are each other's complements and that runs with 100MHz?

It can be what ever model, only that it has nominal single ended voltage from 0 to 0.7 V, and is 100 MHz.

I need such signal in order to simulate crosstalk effects.

Regards, Marko

Got it !,

We have the XIO3130 which is a PCIe-to-PCIe bridge. See terminals DN_REFCKO. (http://www.ti.com/lit/ds/symlink/xio3130.pdf)

See attached file.
