15.1 Overview of RF Transceiver
The RF transceiver supports the Bluetooth ver.4.1 Specification (low energy, single mode).
The analog block consists of a low noise amplifier (LNA), mixer, ADC, power amplifier (PA), and frequency synthesizer
(PLL).
The digital block consists of whitening, CRC, and AES CCM encryption functions, and enables master or slave
operation of the Bluetooth Low Energy in single mode (Bluetooth ver.4.1 Specification).
The features of each block are shown in the following.
