Broadcom Inc. announced the lowest power L1/L5 GNSS receiver chip, the BCM4778, optimized for mobile and wearable applications. Equipped with the latest GNSS innovations, this third-generation chip is 35% smaller and consumes 5 times less power than the previous generation. Dual-frequency GNSS continues to be an important location feature for modern mobile and wearable devices as it provides greater positioning accuracy for location-based services (LBS) applications. The advanced L5 signal enables sidewalk-level accuracy for pedestrian navigation in urban environments, as well as lane-level accuracy for vehicle navigation. Reduction in GNSS power consumption is crucial to extending the battery life of a mobile or wearable device. Compared to GNSS receivers used in integrated platforms, Broadcoms single-chip BCM4778 delivers significantly lower power consumption and higher performance while offering more advanced GNSS features, such as the next-generation Grid Tracking urban multipath mitigation technology. Further, the BCM4778 increases the GNSS always-on battery lifetime on a smart watch by 30 hours when compared to the previous generation chip operating on a 300mAh battery. The extended battery life benefit helps drive new experiences in smart watches and phones. For example, smart watches can keep the GNSS always-on for fitness applications for multiple days on a single battery charge. In addition, the BCM4778 features fully integrated LNAs for L1 and L5 bands, which reduces RF front-end BOM costs and footprint requirements, ideal for space-constrained applications. The chip offers immense flexibility to smart watch and phone designers with its small size. Having the ability to place the BCM4778 closer to the antenna helps improve signal reception and thereby enhance the overall GNSS performance. Product Highlights are 7nm CMOS technology; Typical power consumption - 4mW L1 band only and 6mW L1+L5 simultaneous; FCBGA package; New Grid Tracking technology- Advanced multipath mitigation and Continuously tracks the full L5 channel; Capable of L5 acquisition - Increased processing capability and throughput; Advanced LTE filtering and jamming mitigation- Enhanced LTE Band 13 and Band 14 filtering and Spoofing and jamming detector; Jamming mitigation through multiband and multi constellation; Reduced BOM cost and footprint - Flexibility in using internal LNAs, Optional operation without interstage SAW filters and Integrated switching regulator with direct connect to battery. Broadcom is currently sampling the BCM4778 to its early access partners and customers.
