SkyTraq has introduced the Venus634LP, claiming it to be the world's highest integration single-chip GPS receiver. The device uses low-power Venus6T GPS architecture.

Measuring 10mm x 10mm x 1.2mm, the Venus634LP integrates LNA, SAW filter, RF front-end, GPS base band, 0.5ppm TCXO, RTC crystal, LDO regulator, and passive components. A complete GPS receiver requires only an antenna and Venus634LP.

Featuring highest integration, 1 centimetre squared footprint, ultra fast TTFF, high sensitivity, and low current consumption, the Venus634LP GPS receiver enables lowest cost of embedding location awareness into portable applications without compromising size, performance, and battery life. It is compatible with both active and passive antenna. The receiver consumes 50mA during signal acquisition and 30mA during full power continuous tracking. Dedicated signal parameter search engine within Venus634LP is capable of performing 8 million time-frequency hypothesis testing per second, offering ultra-fast 1-second hot start and 29-second cold start under open sky. Advanced track engine allows tracking sensitivity of -158dBm, enabling continuous navigation in harsh environments such as urban canyon and under deep foliage.

Venus634LP is housed in 10mm x 10mm x 1.2mm 44-pin LGA package. Volume delivery to customer begins in Q3 of 2008. Engineering sample, datasheet, reference design, and evaluation kit will be available in June 2008.
