FEATURES GPS receiver in 10mm x 10mm x 1.2mm size 51 channel acquisition engine 14 channel track engine 8 million time-frequency hypothesis testing per sec Open sky hot start 1 second Open sky cold start 29 second Signal detection better than -158d Bm Reacquisition sensitivity - 155d Bm Accuracy 2.5m CEP ~30m A in tracking and navigation mode Multipath detection and suppression LGA44 package with 0.8 pitch Ro HS pliant The Venus634LP is a plete 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 Venus634LP consists of LNA, SAW filter, Venus120 GPS RF front end, Venus6 GPS baseband, 0.5ppm TCXO, 32.768k Hz RTC crystal, RTC LDO regulator, and passive ponents. It requires very low external ponent 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. With very fast signal acquisition speed, the Venus634LP has very low average power consumption for locate on demand type of applications.
