Beijing, China, September 16, 2015 - Broadcom , the global leader in innovative solutions for wired and wireless communications semiconductors (NASDAQ: BRCM), today announced the launch of the latest Global Navigation Satellite System (GNSS) for the Internet of Things and wearables chip. This advanced chip not only supports devices such as fitness bracelets, but also allows precise positioning with minimal power consumption, and in some cases eliminates the need for a separate microcontroller. For more news, please visit Broadcom's press room.
Broadcom BCM47748 can significantly reduce system power consumption by calculating the position, velocity and time (PVT) on the chip to transfer a large amount of signal processing from the microcontroller. The chip uses intelligent firmware to not only extend battery life, but also maintain accuracy in speed, distance and position calculations to enhance the user experience.
Prasan Pai, senior director of Broadcom's wireless connectivity business, said: "Broadcom helps customers achieve an excellent positioning experience without affecting battery life or high cost, high-power main processor, thus leading us in navigation technology. The status extends to the Internet of Things industry environment. Nowadays, more and more consumers want to deploy GNSS in a wider range of applications. We have seen huge opportunities to expand Broadcom's business to new devices with market-leading GNSS technology."
By implementing on-chip positioning calculation technology, Broadcom not only reduces power consumption, but also replaces the microcontroller and reduces board space, thereby significantly reducing the cost for original equipment manufacturers (OEMs). In addition, the firmware inside the BCM47748 automatically adapts to user activities and situations, whether it is cycling, walking or running, providing users with accurate position results for superior performance at low power.
Main features :
· Calculate position, speed and time (PVT) on the chip
· Integrated GNSS receiver supports both GPS and GLONASS, combined with accelerometer inputs for stable, accurate and low power speed and distance calculation performance
· Context engine and adaptive firmware enable low power consumption in every activity and in any situation without compromising accuracy
· In some cases, GNSS positioning can be generated with only 5 mA of current consumption
· MCU host interface includes SPI, UART or I2C
· Sensor interface includes I2C master, SPI master, I2S, ADC and GPIO
· Large on-chip memory for improved PVT accuracy and enhanced customer applications
· Embedded processor with self-start function
· Geofence and vital record functions
· 70-ball WLBGA package with a ball pitch of 0.4 mm
From September 14th to 18th, 2015, Broadcom Stephen Mole will give a speech entitled “How to achieve low power consumption for wearable devices†at the American Navigation Society (ION) GNSS+ 2015 conference held at the Tampa Convention Center in Florida. Stephen will give a presentation at the A5 session (using consumer GNSS applications) and welcome to attend the event venue, Conference Room 23, at 9:40 am on Friday, September 18.

Emphasis: Because of the market chaos and the cheating of bad dealers, most people simply don't understand USB 3.0 and USB 3.1. USB 3.1 Gen1 is USB 3.0. And USB 3.1 Gen2 is the real USB 3.1. The maximum transmission bandwidth of USB 2.0 is 480 Mbps (i.e. 60MB/s), USB 3.0 (i.e. USB 3.1 Gen1) is 5.0 Gbps (500MB/s), and USB 3.1 Gen 2 is 10.0 Gbps (although the nominal interface theoretical rate of USB 3.1 is 10Gbps), but it also retains some bandwidth to support other functions, so it has a good performance. The actual effective bandwidth is about 7.2 Gbps. USB 2.0 is a four-pin interface, and USB 3.0 and USB 3.1 are nine-pin interfaces.
USB 3.1 is the latest USB specification, which was initiated by big companies such as Intel. Compared with the existing USB technology, the new USB technology uses a more efficient data encoding system and provides more than twice the effective data throughput (USB IF Association). It is fully downward compatible with existing USB connectors and cables.
USB 3.1 is compatible with existing USB 3.0 software stacks and devices

Intel, which owns Thunderbolt technology, also welcomes the formation of the USB 3.1 standard. USB 3.1 contains most of the features of USB 3.0 [2]. USB 3.1, as the next generation of USB transmission specifications, is commonly referred to as "SuperSpeed+", which will replace USB 3.0 in the future. [3]
