Broadcom links Bluetooth to Qualcomm CDMA chip sets
WAYNE, N.J. — Broadcom is looking to increase the penetration of its Bluetooth technology into the CDMA handset market with the release of the Blutonium BCM2004, a single-chip CMOS Bluetooth radio chip that links up with Qualcomm's popular mobile station modem baseband chipsets.

Compliant with the Bluetooth 1.1 and 1.2 specs, the BCM2004 is an integrated transceiver that incorporates a fractional-N frequency generator to synthesize all standard reference frequencies required for implementing a Bluetooth radio in mobile phone designs.

The chip's receiver front-end consists of a low-noise amplifier and an image-reject mixer. On the transmit front, the chip filters and upconverts signals using quadrature local-oscillator signals. Four output power levels can be digitally programmed from full power to low power in 4-dB steps. The chip also includes a transmit/receive switch and associated matching circuits.

The BCM2004 is controlled via Qualcomm's baseband interface. This interface defines data transfers and allows access to various internal registers on the BCM2004.

The BCM2004 is offered in multiple packaging options, including a chip-scale package. The product is currently shipping to Broadcom's early access partners.
