Part Number: CC1312R


hello
My customer want to use the XCC1312R1F3RGZR for 477MHz Sub Giga module.
but They are need the minimum TX Bandwith Spec for KC Certification.
What is the minimum TX bandwidth?
or Is there use case of KC certification?
They are request down to 8.5Khz for TX Bandwidth.
Regards.

    Louis,

    The CC1312R has a programmable TX data rate down to below 1Kbps, this will enable occupied bandwidths of less than 8.5KHz as required by your customer. The RX filter bandwidth is also selectable down to below 4KHz.

    To enable this your customer will need to be running of a TCXO as the drift of a normal XTAL will make this not useful, our new Launchpad's that support the production silicon will come with a TCXO on the boards from the factory. (support for the TXCO is in the chip today, but we lack the software to enable it.)

    Regards,
