Broadcom Corp. has began the sampling of what it claims to be the industry's first Bluetooth product to combine Bluetooth 2.1 features, enhanced data rate (EDR) technology and a Class 1 RF transceiver in a single, monolithic chip.

The BCM2046 supports the most advanced Bluetooth features to provide short-range wireless connectivity for a variety of mobile phones, notebook and desktop computers, PDAs and wireless peripherals. It is also said to be the industry's most highly integrated Bluetooth product, which can reduce external BOMs by more than 80 per cent. BCM2046 integrates on-chip RF matching circuits, balun and power amplifier.

Broadcom's BCM2046 Bluetooth device supports the new Bluetooth 2.1 specifications to extend battery life, simplify pairing and enhance security. As the latest major revision to the Bluetooth specification, version 2.1 is expected to radically simplify the set-up and use of handsets and other products that incorporate Bluetooth, while improving the overall user experience. In particular, BCM2046 implements the "simple pairing" and "enhanced inquiry response" elements of the 2.1 specification, which were designed to address difficulties some consumers encountered when configuring Bluetooth devices.

The combination of BCM2046 silicon with Broadcom's BTW, BTE-Mobile and BTW-CE software provides OEMs with a highly flexible total technology platform that can enable a full range of Bluetooth applications.

BCM2046 also supports EDR technology, which is an industry-standard feature that triples wireless throughput. Bluetooth products with EDR can be used for more advanced multi-media applications, such as streaming music to multiple headsets or wireless speakers, but remain compatible with legacy devices at lower data rates.

In addition to improving throughput, BCM2046 addresses previous limitations on the quality and range of Bluetooth links. Broadcom's Class 1 device offers unparalleled receiver sensitivity and transmitter output power to maintain Bluetooth connections at greater distances—up to 10 times farther than Class 2 solutions. Class 1 devices also use higher output power to combat interference and reduce dropped connections that result from distance and physical obstructions.

Pricing is available upon request. Samples are available to early access customers.
