Broadcom has recently demonstrated the latest combo chip solution at the Mobile World Congress in Barcelona, ​​Spain. The solution provides location-based services (LBS) and advanced multimedia processing capabilities in a single-chip design. Compared to competing solutions, this state-of-the-art connectivity processor dramatically reduces the amount of processing required for host and application processing, enabling a wider range of applications in mass-market handsets.

The Broadcom BCM2075 combo chip integrates four wireless units (Bluetooth, GPS, and FM transmit and receive) with the company's unique InConcertTM coexistence technology that works simultaneously and provides the most compelling with minimal interference. user experience.
Robert A. Rango, senior vice president and general manager of the Wireless Connectivity Division at Broadcom, said: "The success of Broadcom's combo chips highlights our strengths in Bluetooth, GPS and FM connectivity technologies, as well as advanced modular architectures. The solution can coexist and run well on the same chip. Our latest BCM2075 combo chip will help promote the development of key mobile applications that network operators and consumers aspire to use, enabling location services and advanced multimedia features. Enter more mid-range phones."
iSuppli's market research expects that GPS-enabled mobile phones will increase significantly, reaching more than 543 million units by 2012. There will be more than 1.2 billion Bluetooth-enabled mobile phones in the same period, and 910 million mobile phones with FM Radio capabilities. . While these technologies will save power and reduce size on a single combo chip, Broadcom is looking to promote the adoption of these technologies in next-generation handsets by offering this market-proven combo chip.
Technical Information
The BCM2075 is a cost-effective solution for portable devices such as cell phones, portable media players (PMPs) and personal navigation devices (PNDs) that integrates Bluetooth, GPS and FM Radio functions with Broadcom launched in October 2008. The BCM2049 (Bluetooth + FM) combo chip is backward compatible. It uses an ARM Cortex?-M3 processor that delivers optimal connectivity and efficient multimedia processing at low power, extending battery life in mobile phones. The BCM2075 enables accurate indoor and outdoor positioning with the support of the Broadcom Global Reference Network (WWRN: World Wide Reference Network), enabling advanced location services wherever users are located.
The Bluetooth core architecture is designed to meet a wide range of features and low power requirements and is fully compatible with version 2.1 and Enhanced Data Rate (EDR) technology. The core uses SmartAudioTM voice enhancement technology, which greatly improves audio quality and range of headphone connections. It also features Broadcom's unique Packet Loss Concealment (PLC) and wideband voice technology for clearer digital voice. Communication compensates for lost packets at the same time.
The BCM2075 supports multiple concurrently transmitted Advanced Audio Distribution Profile (AADP) streams with Broadcom's BTE-Mobile, Windows Mobile® and Android software packages, enabling music sharing between multiple stereo Bluetooth headsets and establishing a wireless Networked music environment. In addition, the BCM2075 features on-chip processing for the most popular multimedia codecs such as MP3, ADC, AAC/AAC+, enabling the host to process 90% of these tasks on the BCM2075, further extending battery life.
The BCM2075 contains all the FM receiver functions required for advanced FM Radio. Its receiver sensitivity is 3dB higher than previous Broadcom products. The BCM2075 is based on Smart RDS (Radio Data Service, European Standard) and RBDS (Radio Broadcast Data System, North American Standard). The processing function enhances the radio signal with excellent tuning and radio search capabilities for the 65MHz to 108MHz global band. The combo chip's feature-rich FM transmitter supports programmable output power and a cutting-edge algorithm that allows users to recommend the best transmission frequency to their car radio or home FM receiver broadcast. The FM transceiver supports a small-sized FM antenna that can be integrated into a mobile phone or a conventional external earphone cable.
The BCM2075's GPS core uses a host-based integrated architecture that distributes processing tasks to the BCM2075 and the main CPU system, minimizing GPS module power consumption and reducing the required power by approximately 50% compared to today's leading solutions on the market. Consumption. Broadcom's GPS technology benefits from nearly 10 years of in-house software development, enabling the fastest first time to locate (TTFF), integrating support for other positioning technologies such as Wi-Fi positioning, providing a reliable and mature user experience .

The BCM2075 GPS/Bluetooth/FM combo chip has begun sampling to early customers. Prices are available upon request.
Design reflects green concept
Broadcom and its foundry partners make the most of the most advanced lithography nodes when manufacturing semiconductor devices. Broadcom has successfully designed solutions with 65nm process technology to enable products with lower power consumption, smaller size and higher product yields, enabling solutions with 90nm and 130nm processes compared to competitors. Significant environmental benefits; at the same time, the number of components required is reduced due to higher integration. On the other hand, Broadcom also supports the guidelines advocated by the industry today, eliminating the use of lead and other harmful substances (such as halogens such as bromide and chlorine) in all products. Broadcom itself has a broad and deep market-tested intellectual property that has the power to drive innovative products into the market while eliminating their negative impact on human health and the environment.
