EVDD, DEVDD
EVDD and DEVDD are analog and digital supply voltage pins of the Atmel
radio transceiver.
AVDD, DVDD
AVDD and DVDD are outputs of the internal 1.8V voltage regulators. The voltage
regulators can be configured for external supply.
For details, refer to
AVSS, DVSS
AVSS and DVSS are analog and digital ground pins respectively. The analog and
digital power domains should be separated on the PCB.
RFN, RFP
A differential RF port (RFP/RFN) provides common-mode rejection to suppress the
switching noise of the internal digital signal processing blocks. At board-level, the
differential RF layout ensures high receiver sensitivity by rejecting any spurious
emissions originated from other digital ICs such as a microcontroller.
A simplified schematic of the RF front end is shown in
Figure 1-2. Simplified RF Front-end Schematic.
The RF port is designed for a 100 differential load. A DC path between the RF pins is
allowed. A DC path to ground or supply voltage is not allowed.
The RF port DC values depend on the operating state, see
state, when the analog front-end is disabled (see
pulled to ground, preventing a floating voltage.
