Fastrax IT430, based on new-generation SiRFstar IV architecture and SiRFaware technology, offers a range of benefits that speeds the inclusion of location-aware features in battery-operated consumer devices.
The complete module is packed into a tiny casing for fitting into various handheld or other battery-powered devices. It features a miniature form factor of only 9.6 x 9.6 x 1.85 mm, which makes it one of the smallest complete GPS modules available.
With the included TCXO, RTC and SAW filter, the number of required external components is reduced to a minimum.
The device is especially suitable for battery-operated devices using 1.8 V internal power regulation. The module consumes 56 mW at 1.8 V in full operation mode. With SiRFaware standby mode it consumes 500 µA in average while enabling TTFF of 1 s.
Other useful power-saving modes are trickle power, advanced power management and push-to-fix modes that can reduce power drain further, even below 10 mW.
The receiver also detects and removes up to eight CW-jammers, which can be caused by eg, clock harmonics on GPS band. In addition, IT420 is designed with a SAW filter before the LNA, which means that it is highly immune to signal blocking.
