Brief
FEATURES
•
Bluetooth Key Features
•
Bluetooth Specification version 2.1 + EDR (up to 3 Mbps)
compliant, with provisions for supporting future specifications
•
Supports extended synchronous connections (eSCO) for
enhanced voice quality by allowing for retransmission of
dropped packets
•
Adaptive frequency hopping (AFH), for reducing radio
frequency interference.
•
Interfaces support—Host controller interface (HCI) using a
high-speed UART interface and PCM for audio data
•
The FM unit supports BSC (Broadcom Serial Control) for
communications, stereo analog output, as well as I²S and
PCM interfaces.
•
Integrates the InConcert™ collaborative WLAN coexistence,
including the 802.15.2 three-wire coexistence support
•
Low-power consumption improves battery life of handheld
devices
•
76-MHz to 108-MHz FM bands and supports European Radio
Data Systems (RDS) and North American Radio Broadcast
Data Systems (RBDS) modulations
•
Supports dual-A2DP for stereo sound
•
Automatic frequency detection for standard crystal and TCXO
values
SINGLE CHIP IEEE 802.11a/b/g MAC/BASEBAND/RADIO WITH INTEGRATED
BLUETOOTH
