As an unit exchange, 1MHz can be considered to be 2Mbps.

It is a power issue with the TMUX. The TMUX7213 takes massive amounts of power during switching under these circumstances. Even with the V+ and V- 100 ohm series resistors, the amount of current drawn by your part is orders of magnitude above specification. Even though the power surge only lasts for around 150 ns, I have to believe that the high current will eventually damage the internal transistors. I tried putting 1K ohm termination to ground as you suggested on the outputs and that didn&#39;t help. Our patches will hopefully be good enough for production, but I worry about the long term effects of the parts switching this way. I will check out the isolated muxes for future projects. Thank you for your time. I don&#39;t consider this solved. I consider it patched.https://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1650319/ts3ddr4000-request-for-maximum-switching-time-and-propagation-delay-for-worst-case-analysis/6364389Fri, 29 May 2026 16:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:fe1507b5-61a4-4a3e-b0dd-09f79d3b3954Yonathan AlvarezHi Allan, If you are looking to evaluate the worst-case scenario for their design, this would be dependent on what the resistive and capacitive loads are approximated to be. If you can provide this information, I can assist with calculating what their worst-case scenario would be.

I am glad that you were able to find a way to mitigate the noise in your system. At the moment, our team not looking into designing muxes for high capacitive loads, as a digital isolator or shielding can be used to mitigate this issue. For future designs, I would recommend checking out TI&#39;s isolated muxes that our isolation team has designed! Those may be a good one chip solution where analog muxes are not Best, Katyhttps://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1650150/txs02612-pin-functionality/6363013Thu, 28 May 2026 18:42:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:72fed6da-1791-47f9-82a6-6e36546e41b7Jack GuanHi Mudide, The device won&#39;t know if the input is CLK or DATA, however it is suggested to use the dedicated CLK channels as it leverages a buffered architecture to help achieve higher speeds than that of the DAT/CMD channels: That said however, the DAT signals will be able to support the 4000KHz as this is within the operating limits of the device. Please also check with the Switching characteristics table to ensure that the other timing req. are acceptable for your application as well.

We have a board layout with 100 ohm resistors on V+ and V- as well as a 1 ohm on the GND pin. Measuring the voltage change at the TMUX7213 pins (after the resistors) is quite enlightening. First capture shows V+, V- and the switch digital signal: Green is V+ post 100 ohm resistor. Violet is V- post 100 ohm resistor. Yellow is the switch signal. Power dropped into the resistor is roughly 360 mW on the V+ and about 40 mW on the V- Here is a screen capture that shows V+ after 100 ohm, GND after 1 ohm, and the switch: Green is V+ after 100 ohm resistor. Violet is GND after 1 ohm resistor. Yellow is the switch signal. You can see that current on the GND pin oscillates from 400 mA to -400 mA and fades in around 150 ns. The implication here is that the power coming in on the V+ pin is partially sunk into the V- and partially into the GND pin. Adding the series resistors takes care of the noise issue we have on our system. However, we&#39;re looking into ways to do what we need to do without the use of analog switches on the drive side. I suggest TI should look into this issue as I expect at least some other customers might be using high capacitive loads. Personally I would love to hear that you are looking into this issue.TMUX7213Test &amp; Measurementhttps://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1650152/ts3usb3031-mhl-usb-signal-swap/6362792Thu, 28 May 2026 16:04:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:e0c1aaec-7afb-4500-8b76-1e0823c191bcHunter BurnhamHi Toshiro, If I understand correctly, you are asking if you can route a USB2.0 signal through the MHL switch, and a 4GBPS MHL signal through on of the USB2.0 switches. Please clarify if this is not your question. This should be ok, the characteristics of each switch are very similar even though they were intended for different protocols. It can be used in many high speed switching use cases other than the USB/MHL case it was originally designed for. -Hunterhttps://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1650319/ts3ddr4000-request-for-maximum-switching-time-and-propagation-delay-for-worst-case-analysisThu, 28 May 2026 14:19:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0a5cabf1-eb99-4dee-b793-c9b08b2ab64fAllan FanPart Number: TS3DDR4000 Hi experts, Customer is checking some spec quesitons for the TS3DDR4000ZBAR.

Instead of routing the clock signal to the dedicated CLK pin, we are planning to use one of the data lines (D0–D5) for the clock connection. Could you please confirm whether this configuration is supported and justify if the device will work reliably in this setup? Additionally does this works in 4000khz speed, please let us know if there are any functional or timing limitations associated with using a data line for the clock signal instead of the dedicated CLK pin. Looking forward to your clarification.TXS02612https://e2e.ti.com/support/switches-multiplexers-group/switches-multiplexers/f/switches-multiplexers-forum/1649728/txs02612-clk-speed/6361098Wed, 27 May 2026 17:19:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:a76dc977-75f4-41c6-9583-12f8e2d82f04Jack GuanHello, I would recommend the TXB0606 for this application.
