Hi Jimmy,
TMUXHS221 can function as demux when used for PCIe gen 5.0 clock channel switching.
We only have 2:1 mux solutions suitable for PCIe. We do not have other pin configurations (4:1 MUX, 4:2 MUX or 8:2MUX). You may be able to cascade 2:1 muxes, but this will increase loss. To compensate for the loss, you may need to use PCIe signal conditioning.
Best,
Stanton

Hi SLW,
Thanks for your great support.
There are still a few questions to ask about TMUXHS221:
1. Does TMUXHS221 support three PCIe Gen5 clk clock architectures: CC, SRIS, and SRNS?
2. I don't understand the meaning of 10 fs for all NOISE_FOLD and PCIe 5.0 CLK filter versions. Does 10 fs refer to the increased RMS Jitter? PCI_Express_Base_5.0 protocol stipulates RMS (Rj) value
3. When TMUXHS221 is used as DEMUX for PCIe 5.0 CLK, have you done relevant tests? When used for PCIe 5.0 CLK in the specification, only the Diagram when used as MUX is drawn
4. When TMUXHS221 is used for PCIe 5.0 CLK, is the Propagation delay measured?
Many Thanks,
Jimmy
