BCM20713 Preliminary Data Sheet
Adaptive Frequency Hopping
Adaptive Frequency Hopping
The BCM20713 supports host channel classification and dynamic channel classification Adaptive Frequency
Hopping (AFH) schemes, as defined in the Bluetooth specification.
Host channel classification enables the host to set a predefined hopping map for the device to follow.
If dynamic channel classification is enabled, the device gathers link quality statistics on a channel-by-channel
basis to facilitate channel assessment and channel map selection. To provide a more accurate frequency hop
map, link quality is determined using both RF and baseband signal processing.
Collaborative Coexistence
The BCM20713 provides extensions and collaborative coexistence to the standard Bluetooth AFH for direct
communication with WLAN devices. Collaborative coexistence enables WLAN and Bluetooth to operate
simultaneously in a single device. The device supports industry-standard coexistence signaling, including
802.15.2, and supports Broadcom and third-party WLAN solutions.
Using a multi-tiered prioritization approach, relative priorities between data types and applications can be set.
This approach maximizes the performance-WLAN data throughput vs. voice quality vs. link performance.
A PA shutdown pin is available to allow full external control of the RF output for other types of coexistence, such
as WIMAX.
Serial Enhanced Coexistence Interface
The Serial Enhanced Coexistence Interface (Serial ECI or SECI) is a proprietary Broadcom interface between
Broadcom WLAN devices and Bluetooth devices. It is an optional replacement to the legacy 3- or 4-wire
coexistence feature, which is also available.
The following key features are associated with the interface:
• Enhanced coexistence data can be exchanged over SECI_IN and SECI_OUT.
• It supports generic UART communication between WLAN and Bluetooth devices.
• To conserve power, it is disabled when inactive.
• It supports automatic resynchronizaton upon waking from sleep mode.
• It supports a baud rate of up to 4 Mbps.
