GPS Receiver Raises Integration Ante

Unveiled as the market's most highly integrated single-chip GPS receiver, the Venus634LP squeezes a LNA, SAW filter, RF front-end, GPS baseband, 0.5-ppm TCXO, RTC crystal, LDO regulator, and passive components into a 44-pin LGA package measuring 10 mm x 10 mm x 1.2 mm. Employing the company's low-power Venus6T GPS architecture, the receiver consumes 50 mA during signal acquisition and 30 mA during full-power, continuous tracking. Its dedicated signal parameter search engine is capable of performing eight million time-frequency hypothesis tests per second, yielding 1s hot start and 29s cold start times under open skies. Other features include an advanced track engine that allows for a tracking sensitivity of -158 dBm. Engineering samples will be available in June with production starting in the third quarter.
