CSR launches SiRFstarIV GSD4e GPS positioning processor
CSR, the world's leading GPS positioning platform provider, recently launched the SiRFstarIV GSD4e GPS positioning processor. The processor is the latest product based on the recently launched SiRFstarIV architecture and aims to redefine the concept of "location awareness" for mobile devices. For the high-performance and micro-power characteristics of SiRFstarIV architecture, GSD4e adds a built-in CPU. SiRFGeoRecov technology is optimized to ensure the continuous positioning awareness of new digital cameras, portable gaming devices, embedded platforms and other consumer devices without the need to call the main processor.
"Incorporating GSD4e into the SiRFstarIV series of products provides users with two options, namely plug-in and host-type breakthrough positioning perception technology, which enables greater flexibility in the development of various mobile devices and further affirms the positioning The status of perception in daily life. â€Kanwar Chadha, CSR marketing director and founder of SiRF, said,“ With its built-in processor, GSD4e simplifies the integration of positioning perception with existing platforms and helps customize differentiated innovative modules and products. The development of the software provides a smooth upgrade solution for the majority of SiRFstarIII â„¢ users. "
In the fourth quarter of 2009, Vincotech, Navman Wireless, Kyocera, Mitsumi, and SEMCO, the world's leading module distributors, are working on designing GSD4e modules, accelerating the launch of SiRFstarIV architecture consumer products.
GSD4e's innovative adaptive accuracy and SiRFGeoRecov technology have promoted the development of pictures and videos that can overlay geographic information at any time. With the improvement of the acquired GPS information, the accuracy of positioning has been greatly improved. At the same time, it helps people locate social network friends through smartphones, use wearable devices to track jogging routes, locate searches through laptops or netbooks, or search for roads through buildings and urban canyons through a walking navigation system. And it is not limited by daily environmental factors, even if the equipment is turned off for weeks or even months, it will not have any impact. Other GPS solutions currently on the market have repeatedly failed to provide positioning. GSD4e ensures that the positioning device is always located in the "location network", even if the signal is extremely bad. GSD4e's cutting-edge mobile sensing algorithm ensures advanced power management and stable and accurate positioning, even in a static environment, without impact.
Compared with other host-based architectures, GSD4e is more widely used, the design is simpler and more flexible, and it is a complete position-rate-time (PVT) solution. It not only drove the emergence of new positioning consumer devices, but also improved the performance of the traditional GPS engine market for mobile phones, GPS modules, multi-frequency modules and similar applications. GSD4e navigation sensitivity -160dBm, tracking sensitivity -163 dBm. For mobile phone users, GSD4e can provide an excellent 7.5-dB 3GPP pass rate and E911 high sensitivity to ensure the successful design of various mobile phone designs. At the same time, it provides a fully certified A-GPS protocol stack that can be quickly applied to many smartphone operating systems. GSD4e requires only 8mW of power in 1-Hz TricklePower mode, and only 50-400μA current in SiRFaware mode, that is, it can continue to maintain a hot start state. The enhancement of the SiRFNavPlus navigation engine can ensure seamless car and walking navigation in extremely harsh urban canyons and densely wooded environments.
GSD4e supports ROM and flash memory, and is the first product to be produced in synchronization with CSR's unique SiRFInstantFix â„¢ integrated ephemeris (syntheTIc ephemeris) technology, with more powerful performance. On-chip active interference removal is the main feature of the SiRFstarIV architecture, which usually not only eliminates electrical noise associated with components in engines, LCD displays and mobile phones, cameras, game consoles and other consumer devices, but also helps designers in the development process Identify the source of the exact strength and interference signal earlier and avoid it during the design phase without having to procrastinate to a more costly test phase. GSD4e also supports complete satellite-based amplification systems such as WAAS, EGNOS, MSAS and GAGAN.
"The ROM version of the GSD4e GPS engine is a low-cost, low-power solution with complete positioning capabilities that can be easily integrated with the processing resources of space and consumer devices." Sunil, Senior Product Sales Manager, CSR Audio and Consumer Business Gopinath said, "The flash memory version can provide users with more CPU resources, more flexible customization, and faster application of new and innovative algorithms of CSR. At the same time, our development tools help customers develop GSD4e processors and flash memory. The user software running on the Internet also increases the customer's ability to innovate independently. "
Gopinath said, "GSD4e has a built-in circuit and temperature adaptation software, which can replace the temperature-compensated crystal oscillator (TCXO). The crystal cost is low, which helps users with material cost (BOM) awareness to use the lowest cost materials on the market. The product is designed for GPS. "
He also mentioned, "GSD4e integrates eFuse technology to help users improve system configuration capabilities by electronically setting custom configurations at system startup, thereby replacing the time-consuming and labor-intensive manual software change methods currently used in products on the market."
The ROM version size is 3.5 mm × 3.2 mm, and the wafer level chip package (WLCSP) size is 42-ball 0.5-mm. The flash memory version has a size of 5 mm × 7.2 mm, and the ball grid array package (BGA) size is 103-ball 0.5-mm.
GSD4e combines an RF receiver with integrated LNA, baseband circuit, converter and single-chip low-current LDOs, requiring only 5-6 external neutral components and a SAW to provide a complete solution. Including the converter part, it occupies less than 25 square millimeters.
Advantages of SiRFstarIV
The core of SiRFstarIV architecture is composed of high-performance GPS positioning engine, intelligent positioning sensor interface, adaptive micro-power manager and active interference remover, and provides:
The industry ’s benchmark SiRFstarIII architecture has twice the search capacity, enhanced sensitivity, shortened positioning time, and improved positioning accuracy
Advanced micro power management and integrated conversion mode rules to maintain hot start conditions at minimum energy (50-400 micro amps)
Intelligent MEMs sensor support (for accelerators and other sensors) improves the positioning experience, contributes to higher environmental awareness, more sophisticated energy management, and enhances the accuracy of indoor positioning
Cutting-edge DSP technology actively searches for jammers and removes them before GPS best performance and design troubleshooting are relevant.
Product supply pricing
