GNSS receiver BCM47531

Broadcom's fourth-generation multi-constellation Global Navigation Satellite System (GNSS) solution, fabricated in low power 40nm CMOS technology, and adding support for BeiDou (BDS) constellation. The BCM47531 builds on the success of the ubiquitous BCM4752 GNSS receiver by providing simultaneous multi-constellation support for the GPS, BDS, GLONASS, QZSS and SBAS constellations. The BCM47531 receiver offers fast time-to-fix in all scenarios, accurate real-time navigation, fast re-acquisition of signals after blockage or tunnel exits and best-in-class sensitivity. This receiver chip continues the ability to have low power consumption even with the addition of acquiring and tracking the BeiDou satellites. An additional capability is always-on low-power geofencing support. The BCM47531 is optimized for standalone GNSS solution for smartphones, tablet computers, Internet-of-things devices and portable navigation devices (PNDs).
