BCM20713 Preliminary Data Sheet
Frequency Hopping Generator
The BCM20713 provides full support for Bluetooth 2.1 + EDR additional features:
• Secure simple pairing (SSP)
• Encryption pause resume (EPR)
• Enhance inquiry response (EIR)
• Link supervision time out (LSTO)
• Sniff subrating (SSR)
• Erroneous data (ED)
• Packet boundary flag (PBF)
Frequency Hopping Generator
The frequency hopping sequence generator selects the correct hopping channel number, based on the link
controller state, Bluetooth clock, and device address.
Link Control Layer
The link control layer is part of the Bluetooth link control functions implemented in dedicated logic in the link
control unit (LCU). This layer consists of the Command Controller that takes commands from the software and
other controllers that are activated or configured by the Command Controller to perform the link control tasks.
There are two major states–standby and connection. Each task establishes a different state in the Bluetooth link
controller. In addition, there are eight substates—page, page scan, inquiry, inquiry scan, park, sniff subrate, and
hold.
Test Mode Support
The BCM20713 fully supports Bluetooth Test Mode, including the transmitter tests, normal and delayed
Loopback tests, and the reduced hopping sequence.
In addition to the standard Bluetooth Test mode, the device supports enhanced testing features to simplify RF
debugging and qualification and type approval testing.
These test features include:
• Fixed frequency carrier wave (unmodulated) transmission
– Simplifies some type approval measurements (Japan)
– Aids in transmitter performance analysis
• Fixed frequency constant receiver mode
– Directs receiver output to I/O pin
– Allows for direct BER measurements using standard RF test equipment
– Facilitates spurious emissions testing for receive mode
