• Timing Generator

- Bluetooth clock generation

- Operation interrupts depend on mode (slot, scan, sniff, hold, park)

- Sync detection timing generation (sync window ±10

µs)

- PLL setting timing generation

- Transmit/Receive timing generation

- Multi-master timing management function

• Packet Composer

- Access code generation (SyncWord generation, appending PR*TRAILER)

- Packet header generation (HEC generation, scrambling, FEC encoding)

- Payload generation (CRC generation, encryption, scrambling, FEC encoding)

- Packet synthesis

• Packet Decomposer

- Packet decomposition (separating the packet header and the payload)

- Packet header processing (FEC decoding, descrambling, HEC error detection, header information

separation)

- Payload processing (FEC decoding, descrambling, encryption decoding, CRC judgement, payload

separation)

• Security

- Various key generation functions (initialization, link key, encryption key)

- Certification function

- Encryption function
