• Manufacturer Part Number: ml70q5110la
• Description: Bluetooth Baseband Controller Ic
• Manufacturer: Oki Semiconductor

Baseband Core Block
OKI Semiconductor
RF Controller
- RF power supply control (PLL, TX, RX)
- Local PLL frequency division ratio setting
- Receive clock regeneration function
- Synchronization detection (synchronizing within the permissable error limit of SyncWord)
- Receive clock re-timing function
FH Controller hopping
- Sequence control
- Frequency hopping selection function
- CRC computation's initial value selection function
Timing Generator
- Bluetooth clock generation
- Operation interrupts depend on mode (slot, scan, sniff, hold, park)
- Sync detection timing generation (sync window ±10 s)
- 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
- Payload processing (FEC decoding, descrambling, encryption decoding, CRC judgement, payload
Security
- Various key generation functions (initialization, link key, encryption key)
- Certification function
- Encryption function
