RF430F5978: LF wake up receiver

Part Number: RF430F5978

Hello,

Do the RF430F5978 and TMS37126D  3D wakeup receiver work at the 65-95 kHz LF frequency band? The spec only talks about the 110-140kHz range. Thanks!

Best,

Adam

    Hello Adam,

    No, they do not. From a wake receiver standpoint, I don't believe we have any device that operates in that range.

    Hello Ralph,

    Thanks for the quick response. For the project, we have problems with interference at 125kHz for LF 3D wakeup receiver.  This receiver jammed by the LF RFID reader which also works at the  125 kHz frequency band.  So we are looking another possibility to use an another frequency 65-95 kHz or 150-200 kHz band. It’s why I explore the RF430F5978 and TMS37126D and will be great to understand how it is flexible and how we can be reconfigurable the 3D wakeup receiver. I know it is beyond the IC standard tech spec, but can be those IC be used in not standard mode (whether lower or higher frequency)? Is there something else you'd recommend?
