SiRFstarIIt Chip Set and SiRFNav Software GPS Tracker Chip Set and Software for Consumer Products FAMILY HIGHLIGHTS ARCHITECTURE HIGHLIGHTS GSP2t- Digital Tracker IC SiRF Chips and Software SiRF's Industry Leading GPS available for Host System Applications Builds on high performance SiRFstarII GPS tracking engine chipset plus navigation software Signal acquisition using 1920 time/frequency search channels SBAS (WAAS, EGNOS, MSAS) support Satellite signal tracking engine performs GPS acquisition and tracking functions Multipath-mitigation hardware Cold Start averages 45 seconds Integrated Signal Processor acquires and tracks satellites autonomously Raw measurements and GPS data output via serialport to host Uses on-chip high precision Real-Time Clock or host processor's RTC Analog to Digital converter for dead reckoning heading gyro or other input Odometer counter and forward/reverse indicator input On-chip UART GRF2i/LP - Low Power RFIC Low Power On-chip VCO and reference oscillator Integrated LNA Uses less than 30mA's of current Simplified digital interface Only 175 mW at full power Snap Start mode allows reduced power fixes Maximizes Position Availability SingleSatTM updates in reduced visibility Superior urban canyon performance FoliageLockTM for weak signal tracking Optional SiRFDRiveTM dead reckoning for continuous, reliable navigation SiRFNavTM Host Processor Software Runs on host system processor and memory Easily portable to multi-thread processors and operating systems Uses 300Kbytes ROM and 100Kbytes RAM, dependent on host Optional SiRFDRiveTM dead reckoning for continuous, reliable navigation Position Accuracy Autonomous SBAS <10m <5m Receiver Tracking Channels Max. Update Rate Sensitivity Max. Altitude Max. Velocity Protocol Support L1, CA code 12 1Hz -172dBW <60,000 ft <1,000 knots SiRF Binary Acquisition Reacquisition Time SnapStart Hot Start Warm Start Cold Start 100msec <3sec <8sec <38sec <45sec Power Full Power Voltage <175mW GRF: 2.85V, GSP: Core 1.8V, IO 3.3V SiRFstarIIt ARCHITECTURE 1 Evaluate SiRFstarIIt makes it easy and economical to add high-performance SiRFstarII technology to systems that are based on many popular processors and operating systems. The SiRFstarIIt solution allows GPS function to be added at minimal cost in components and circuit board area, by sharing the host system's processor, memory resources and Real TIme Clock. The chipset acquires and tracks satellites, then sends raw measurements to the host processor running the SiRFNav software in parallel with the host applications. The SiRFNav software module computes position time and velocity. For enhanced accuracy and navigation reliability, SiRFDRive dead reckoning data and SBAS corrections can also be processed.

SiRF Taiwan +886 2 2723 7853 tomlin@sirf.com LNA GRF2i/LP GSP2t ADC Counter I/O User App. Code (Optional) RF Filter The GSP2t's on-chip wheel tick counter and analog to digital convertor for heading gyros make the SiRFstarIIt particularly well suited to automotive applications. The SIRFDRive closely coupled dead reckoning software combines GPS and DR measurements to provide continuous and accurate navigation in the most challenging operating environments such as urban canyons and tunnels. GPS measurements calibrate the dead reckoning sensors allowing the use of economical hardware, while dead reckoning data optimizes and cross-checks the GPS solutions. 2-Bit Host CPU 3 REF XTAL AGC Serial Data GUI 2.85V The SiRFstarIIt is designed to be embedded into large volume applications that use multi-thread processors and real time operating systems. The SiRFstarIIt hardware can be added to the host motherboard within an area smaller than two centimeters square, and with minimal increment in bill of material. The accurate positioning and optinal built in dead reckoning sensor support provide optimum performance for automotive navigation and telematics systems. Small size and low cost also make the SiRFstarIIt the solution for portable devices such as hand-held navigators and Personal Digital Assistants where space and cost are critical. WORLDWIDE SALES OFFICES SiRFstarIIt BLOCK DIAGRAM Develop APPLICATIONS DIGITAL CHIP PACKAGE The chipset consists of the GSP2t, highly integrated digital chip, GRF2i/LP integrated RF receiver and the SiRFNav software. The GSP2t is packaged as 7mm 48 pin LQFP packages and the GRF2i/LP is in a 5mm 32 pin QFN package. External components are minimized thanks to their high level of integration. SiRFNav software is designed for easy porting to most common host systems. 2 Build TECHNICAL SPECIFICATIONS GPS CLKS SiRF's technology is protected by U.S. and foreign patents pending and issued.
