Venus 634LP All-In-One Single-Chip GPS Receiver

With very fast signal acquisition speed, the Venus634LPx has very low average power consumption for locate on demand type of applications.

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.

The Venus634LPx consists of Venus121 GPS RF front end, Venus6 GPS baseband, 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. 

The Venus634LPx is a complete 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.
