Bluetooth Power Management Unit
Bluetooth Power Management Unit
The Bluetooth Power Management Unit (PMU) provides power management features that can be invoked by
either software through power management registers or packet handling in the baseband core. The power
management functions provided by the BCM4330 are:
• RF Power Management
• Host Controller Power Management
• BBC Power Management
• FM Power Management
RF Power Management
The BBC generates power-down control signals for the transmit path, receive path, PLL, and power amplifier
to the 2.4 GHz transceiver. The transceiver then processes the power-down functions accordingly.
