1. Description The AT86RF215 is a multi-band radio transceiver for various sub-1GHz bands and the 2.4GHz band specially designed for smart metering and applications implementing IEEE Std 802.15.4g™-2012 [3], ETSI TS 102 887-1 [5], IEEE Std 802.15.4TM-2015 [7]. The device is comprised of two independent transceivers, each with its own baseband and I/Q data interface. The AT86RF215 incorporates two transceivers and two baseband cores forming two independent radio systems. The transceivers are highly integrated minimizing the number of external components required on the printed circuit board (PCB)....

Control Logic and Naming Conventions Both radio and baseband cores have separate register blocks. The sub-1GHz radio register names are prefixed by “RF09_”. The 2.4GHz radio transceiver register names are prefixed by “RF24_”. The register descriptions, including sub-register descriptions, for both radios and their respective basebands are identical. In rare cases where a register is only valid for one specific radio (or baseband), the register for the other radio (or baseband) is ignored. The baseband processor Core0 is connected to the sub-1GHz radio and Core1 is connected to the 2.4GHz radio....

2.2.1 RFP09/RFN09, RFP24/RFN24 The differential RF pins (RFP09/RFN09; RFP24/RFN24) provide common-mode rejection to suppress the switching noise of the internal and external digital signal processing blocks. A 500 differential load at the RF ports ensures high sensitivity and output power. A DC path between the RF pins is supported; a DC path to ground or supply voltage is not supported. When connecting an RF load providing a DC path to the power supply or ground, AC coupling is required. The pins RFP24/RFN24 of AT86RF215M are shortened to AVSS internally and may not be connected. 2.2.2 EVDD,...
