TEST MODE SUPPORT
The BCM4325 fully supports Bluetooth Test mode as described in Part 1 of the Specification of the Bluetooth System
Version 2.1. This includes the transmitter tests, normal and delayed loopback tests, and reduced hopping sequence.
In addition to the standard Bluetooth Test Mode, the BCM4325 also supports enhanced testing features to simplify RF
debugging and qualification and type approval testing. These features include:
•
Fixed frequency carrier wave (unmodulated) transmission
-
-
Simplifies some type approval measurements (Japan)
Aids in transmitter performance analysis
•
Fixed frequency constant receiver mode
-
-
-
Receiver output directed to I/O pin
Allows for direct BER measurements using standard RF test equipment
Facilitates spurious emissions testing for receive mode
•
Fixed frequency constant transmission
-
-
8-bit fixed pattern or PRBS-9
Enables modulated signal measurements with standard RF test equipment
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 BCM4325 are:
