Venus634LPx-T 65 Channel Timing Mode GPS Receiver
FEATURES
Complete GPS receiver module in 10 x 10 x 1.1 mm
51 channel acquisition, 14 channel tracking
8 million time-frequency hypothesis testing per sec
Open Sky hot start 1 second, cold start 29 second
Signal detection sensitivity -161dBm
30nsec (1-sigma) timing accuracy
Position hold mode for GPS timing operation
1PPS generation with 1 satellite in view
~28mA operating current
0.8mm pitch LGA44 package, RoHS compliant
The Venus634LPx-T is a high performance module in a
chip design targeting precision timing GPS receiver
application. It offers very low current consumption, high
sensitivity, and best in class signal acquisition and time to
first fix performance.
The Venus634LPx-T 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
continuous reliable precision timing generation in harsh
environments such as urban canyons and under deep
foliage.
