TMUX121: Clarification on TMUX121 Support for SD 3.0 and PCIe Clock Switching

Part Number: TMUX121

Tool/software:

Dear TI team,

We are planning to use the TMUX121 in our design and would like your confirmation on the following points:

Design Requirements:

DAT0, DAT1: 104 Mbps single-ended signals (from SD 3.0 interface)

CLK_P, CLK_N: 100 MHz differential PCIe clock (HCSL signaling)

The above table is reference for signal connections by using TMUX121

  • When SEL = 0 → D1/D2 are connected to S1A/S2A (SD 3.0 mode)

  • When SEL = 1 → D1/D2 are connected to S1B/S2B (PCIe mode)

    Questions based on our design requirements:

  • Can the TMUX121 support 104 Mbps single-ended signals on the source and drain pins?

  • Can The TMUX121 handle a 100 MHz differential ended PCIe clock (HCSL) on the source and drain pins ?

  • Are the source and drain pins compatible with 1.8 V I/O levels?

    Note: Request you to revert back at the earliest
