Venus868F is a high performance, low cost, single chip
GPS/Beidou receiver targeting mobile consumer and
cellular handset applications. It offers very low power
consumption, high sensitivity, and best in class signal
acquisition and time-to-first-fix performance.
Venus868F contains all the necessary components of a
complete GPS/Beidou receiver, includes RF front-end,
GPS/Beidou baseband signal processor, 0.5ppm TCXO,
32.768kHz RTC crystal, RTC LDO regulator, and passive
components. It requires very low external component
count and takes up only 100mm
2
PCB footprint.
Dedicated massive-correlator signal parameter search
engine within the baseband enables rapid search of all the
available satellites and acquisition of very weak signal. An
advanced track engine allows weak signal tracking and
positioning in harsh environments such as urban canyons
and under deep foliage.
The self-contained architecture keeps GPS/Beidou signal
processing off the host and allows integration into
applications with very little resource.
Venus868F is very easy to use, minimizes RF layout
design issues and offers very fast time to market.
