| LMX5452: integrated baseband controller and radio National Semiconductor. Powering the wireless world. Bluetooth Bluetooth wireless solutions Everyone wants to be connected. At home. At work. At play. And National Semiconductor is pioneering wireless solutions across the board. From high-performance, optimized ICs to complete reference designs--National's Bluetooth technology is enabling wireless communications anytime, anywhere. Bringing you a world of fast and secure wireless connectivity between consumer electronics, cellular phones, PCs, and peripherals-- National is at the forefront of Bluetooth innovation, making tomorrow's technology a reality today. Introducing the next generation in Bluetooth(R) solutions National's LMX5452 provides the features and functionality designed to get you to market faster, offering a more cost effective solution than ever before. This highly integrated solution combines a 0.18 m CMOS Bluetooth baseband controller and 2.4 GHz radio. Available in a single tiny BGA-60 package (6 mm x 9 mm), the LMX5452 provides one of the smallest solutions available in the industry. It is optimized to handle the audio, data and link management processing requirements of a Bluetooth node. The baseband controller features ROM to reduce system cost and patch RAM to minimize risk and allow for easy customization and firmware upgrades. It features a Bluetooth Link Manager and HCI connection over USB or UART, and is designed to operate at full Bluetooth data rates of 723 kbps. Radio Featuring an integrated antenna filter and switch, National's radio minimizes the total number of external components. The radio additionally integrates the receiver and transmitter baluns, the antenna switch, and filter together with the VCO onto a tiny single die. The fractional-N deltasigma synthesizer and the crystal offer support for a wide range of external reference frequency clocks and crystals. Baseband controller An extension of the industry-proven LMX5100, the baseband controller features a standard Host Controller Interface (HCI), and is based on National Semiconductor's CompactRISCTM 16-bit processor.
