Abstract:
A high performance RFCMOS SoC GPS navigation solution is introduced. It supports various location and navigation applications, including autonomous GPS, SBAS, DGPS (RTCM), and AGPS in L1-band at 1575.42MHz. A wide range of reference frequencies are supported to comply with other handheld specifications. The base-band architecture is optimized for the correlation efficiency and the power consumption of one single correlating operation. Hence this SoC receiver achieves the industry's highest levels of sensitivity, accuracy, and Time-to-First-Fix (TTFF) with the lowest power consumption. PMIC is also integrated in the SoC, no external LDO and power switching circuit is needed for all voltage domains, including RTC.
