The Venus634FLPx is a module-in-a-chip design targeting
mobile consumer and cellular handset applications. It
offers very low current consumption, high sensitivity, and
best in class signal acquisition and time-to-first-fix
performance.
The Venus634FLPx contains all the necessary
components of a complete GPS receiver module, includes
GPS RF front-end, GPS 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 100mm2
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.
Programmable flash-based memory makes it ideal for
applications requiring customized firmware.
