12 Application Schematic Introduction

The SAM R30 Application schematic has to provide the environment for both integrated circuits inside the package. The micro controller as well as the radio have integrated LDO's to provide the required core voltages. To achieve the full radio performance the application layout has to take the noise decoupling in between the analog radio part and the digital processor and signal processing power domains into account. To avoid noise interference with the radio part, the switch regulator is not available in this version of SAM L21.
