Original question:

TS3A27518E: about 240MHz bandwidth

TS3A27518E: Application of TS3A27518E

Part Number: TS3A27518E

Hi TI Teams,

Our project requires the use of two SPI flashes, compatible with wire brushes, and we plan to use two TS3A27518E for this application, the schematic block diagram is as follows:

Is this design feasible? Or do you have any better suggestions?

Thanks,

Kind Regards

    Hi Lumina,

    If the frequency of the SPI signals you're using are ~50 MHz, then this application should be just fine. Cascading muxes can reduce your effective bandwidth by half, but even at 120 MHz, this is plenty of headroom for 50 MHz signals. Other than that, I think this design looks good.

    Thanks!
