Data Sheet SKYTRAQ VENUS634FLPx 65 Channel Low Power GPS Receiver --- Flash FEATURES z z z z z z z z z z z z z GPS receiver in 10mm x 10mm x 1.1mm size Tests 8 million time-frequency hypothesis per sec Open sky cold start 29 second Signal detection better than -161dBm Accuracy 2.5m CEP ~28mA in tracking and navigation mode Multipath detection and suppression Data logging with external SPI serial Flash Supports active or passive antenna 1 SPI interface and 7 GPIO lines Flash-based, firmware customizable LGA44 package with 0.8 pitch Pb free RoHS compliant The Venus634FLPx is a module-in-a-chip design targeting mobile consumer and cellular handset applications. It offers very low current consumption, high sensitivity, and best in class signal acquisition and time-to-first-fix performance. The Venus634FLPx contains all the necessary components of a complete GPS receiver module, includes GPS RF front-end, GPS baseband signal processor, 0.5ppm TCXO, 32.768kHz RTC crystal, RTC LDO regulator, and passive components. It requires very low external component count and takes up only 100mm2 PCB footprint. Dedicated massive-correlator signal parameter search engine within the baseband enables rapid search of all the available satellites and acquisition of very weak signal. An advanced track engine allows weak signal tracking and positioning in harsh environments such as urban canyons and under deep foliage. Programmable flash-based memory makes it ideal for applications requiring customized firmware.
