HD3SS3415, is there an extended temperature range version available or a suitable alternative?

Other Parts Discussed in Thread: HD3SS3415, HD3SS3411

Hi,

I've used a large number of TI parts in the clocking/redriving, high speed EQ and other switching device ranges and have normally had no problems locating a component that exists in the extended or industrial operating temperature range. I've come across the HD3SS3415 part which is ideal for a design that I am currently working on other than the fact it appears to be commercial temp only.

In the proposed application of this part, it would need to operate as low as -50C and as high as 125C. I have previously found that when not changing parameters on these devices, I have been able to use the industrial range without too much trouble. Does an extended temperature range variant exist or can you point me to a viable alternative.

Kind regards,

Chris

    Hi Chris,

    This device was first released as industrial grade temp(-40°C to 85°C) but we found that under certain circumstances there were issues when working in extreme temperatures that's why we decided to change the guaranteed supported temperature range to commercial value (0°C to 70°C).
    The only other option on industrial temp we have is the HD3SS3411 but that one has only one MUX/DEMUX.

    Regards.

    Hi Jose,

    Thanks for the information, it is handy to know. My intention is to use these parts as a pre-configured option switch for high speed signalling (PCIe Gen3, Sata3.0, USB 2/3, TMDS video (DVI/HDMI)) before running electronic tests on the system.

    As I do prefer TI as a manufacturer compared to the alternatives I have found, is an application where the the switch is set once, then put into an environment where the temperature will be ramped up and down as part of an ESS style test going to break the device or would I need to prototype this in order to determine suitability for my intended application.

    Kind regards,

    Chris

    Hi Chris,

    I think it would be hard to tell if it's going to break the device without knowing all parameters and even having all parameters, those will have to match with the ones we have measured in characterization so we could tell.

    I think the best you can do is to prototype it in order to determine suitability in your application.


    Best regards.
