19.1 Block Diagram
The RYZ012 integrates an advanced Bluetooth LE/802.15.4/2.4GHz RF transceiver. The RF transceiver works in the worldwide 2.4GHz ISM
(Industrial Scientific Medical) band.
The transceiver consists of a fully integrated RF synthesizer, a Power Amplifier (PA), a Low Noise Amplifier (LNA), a TX filter, a RX filter, a TX
DAC, an ADC, a modulator and a demodulator. The transceiver can be configured to work in standard-compliant 1Mbps Bluetooth LE mode,
2Mbps enhancement Bluetooth LE mode, 125kbps Bluetooth LE long range mode (S8), 500kbps Bluetooth LE long-range mode (S2), IEEE
802.15.4 standard-compliant 250kbps mode, and Proprietary 1Mbps, 2Mbps, 250kbps and 500kbps mode.
The internal PA can deliver a maximum 10dBm output power, avoiding the need for an external RF PA.

19.2 Baseband
The baseband is disabled by default. The corresponding API is available for user to power on/down the baseband and enable/disable clock, so
that the baseband can be turned on/off flexibly.
The baseband contains dedicated hardware logic to perform fast AGC control, access code correlation, CRC checking, data whitening,
encryption/decryption and frequency hopping logic.
The baseband supports all features required by Bluetooth 5 and 802.15.4 specification.
