SkyTraq has introduced Venus634LPx GPS receiver that features improved cold start sensitivity of -148 dBm, better tracking sensitivity of -161 dBm, lower full-power tracking current of 23 mA and a smaller LGA44 package.

The device contains all the necessary components of a GPS receiver, including GPS RF front-end, 65-channel GPS/AGPS baseband processor, 0.5 ppm TCXO, RTC crystal, LDO regulator and passive components.

A complete GPS receiver requires only antenna, Venus634LPx and few external passive components.

Featuring a 29 s cold start TTFF, -161 dBm tracking sensitivity and 23 mA current consumption, the integrated ROM-based device enables low-cost embedding location awareness into portable applications without compromising size, performance and battery life. It is compatible with both active and passive antennas.
