Venus 638

Reference: Venus 638 (ask a question)

The Venus638 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 Venus638 contains all the necessary components of a complete GPS receiver module, includes 1.2dB
cascaded system NF 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.
