Which radio is this?

[jrdoner]

I am confused.   I downloaded the RFM69W data sheet, which appears to be a product of HopeRF.   But in looking over the include files, I find the SemTech SX1231H referenced. So, are these completely interchangeable, and either data sheet applies, or what is the situation?

Thanks in advance for any insights.
