BCM2004

Product catalog summary

Overview: The BCM2004 is a Bluetooth transceiver optimized for use in QUALCOMM MSM-based wireless systems. It is compliant with Bluetooth versions 1.1, 1.2, and 2.0, and supports simultaneous operation with GPS, WCDMA, CDMA, and GSM/GPRS radios. The transceiver is implemented in digital CMOS and features fractional-N frequency generation technology for synthesizing industry-standard reference frequencies.

Specifications: The BCM2004 achieves a receiver sensitivity of -88 dBm under high interference conditions and provides up to +4 dBm output power. It supports Class 2 or 3 operation and features enhanced spurious emissions and cellular blocking performance. The device is fabricated in standard bulk CMOS and includes built-in self-calibration and temperature compensation.

Integration and Design: The transceiver includes a fully integrated RF front-end matching circuit, eliminating the need for external baluns and T/R switches. It supports operation from 1.8V to 4.6V and features advanced packaging options, including wafer scale chip size package and fine pitch ball grid array, to simplify integration into small form factor handsets.

Performance and Benefits: The BCM2004 offers low active power consumption and a single-digit standby current. It provides the highest level of system integration, eliminating all external active and critical components, thus reducing the total BOM cost. The device's small footprint minimizes board area and height requirements.

Control and Interface: The BCM2004 is controlled via a QUALCOMM proprietary baseband interface, which manages the chip's various sections, data transfers, and access to internal registers.
