Bluetooth Baseband Controller
A 16-bit CRC is adopted to protect payload data transmitted using certain types of
Bluetooth packets.
7.5.7 Encryption/Decryption core
Information confidentiality can be protected by encryption of the packet payload.
Dedicated encryption/decryption hardware is designed into the baseband core.
7.5.8 Authentication
The authentication in Bluetooth is based on SAFER+ algorithms. Effective architecture is
implemented in hardware.
7.5.9 Received Signal Strength Indicator (RSSI) metric
The RSSI value is provided to the baseband processing hardware through an eight bit
ADC (analog to digital converter).
7.5.10 Available Operating Clock Frequencies
The ISSC IS1090 chip is capable of operating at the following frequencies: 48 MHz, 36
MHz, and 24 MHz. The following table shows the correct configuration for each frequency.
