Venus638FLPx GPS Receiver Data Sheet 10mmx 10mm Venus638FLPx-L / Venus638FLPx-D SkyTraq Technology, Inc. www.skytraq.com.tw empower mobility, without uncertainty 1 FEATURES Venus638FLPx is a high performance, low cost, single 20Hz update rate chip GPS receiver targeting mobile consumer and cellular handset applications. It offers very low power -148dBm cold start sensitivity consumption, high sensitivity, and best in class signal acquisition and time-to-first-fix performance. -165dBm tracking sensitivity 29 second cold start TTFF Venus638FLPx contains all the necessary components of a complete GPS receiver, includes 1.2dB cascaded 3.5 second TTFF with AGPS system NF RF front-end, GPS baseband signal processor, 0.5ppm TCXO, 32.768kHz RTC crystal, RTC LDO 1 second hot start regulator, and passive components. It requires very low 2 external component count and takes up only 100mm 2.5m accuracy PCB footprint. Multipath detection and suppression Dedicated massive-correlator signal parameter search Jamming detection and mitigation engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An SBAS (WAAS / EGNOS) support advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons 7-day extended ephemeris AGPS and under deep foliage. 67mW full power navigation The self-contained architecture keeps GPS processing off Works directly with active or passive antenna the host and allows integration into applications with very little resource. Internal flash for optional 75K point data logging Supports external SPI flash memory data logging Venus638FLPx is very easy to use, minimizes RF layout design issues and offers very fast time to market. Complete receiver in 10mm x 10mm x 1.3mm size Contains LNA, SAW Filter, TCXO, RTC Xtal, LDO Pb-free RoHS compliant Product Series Product Description Venus638FLPx-L Flash version GPS receiver (internal 1.2V LDO version) Suitable for Venus634FLPx direct drop-in replacement Venus638FLPx-D Flash version GPS receiver (external 1.2V version) Suitable for lower power application using external 1.2V supply SkyTraq Technology, Inc. www.skytraq.com.tw empower mobility, without uncertainty 2
