GRF2I Description

Short technical summary and product information.

The SiRF GRF2I is a low-power GPS chip set, part of the SiRFstarIIe/LP architecture, designed for high-volume consumer applications. This integrated front-end component, paired with the GSP2e/LP digital chip, provides 40 MIPS of processing power and utilizes 1920 correlators across 12 channels for rapid acquisition and re-acquisition times.

 

Key features include TricklePower technology, which extends battery life by reducing average current consumption to under 20mA, and peak current draw under 65 mA. The GRF2i/LP itself consumes less than 30 mA. It supports advanced performance features such as SingleSat, SnapLock, and FoliageLock for enhanced GPS position availability, even in challenging environments like urban canyons or under foliage.

 

This chip set is suitable for standalone GPS products and supports SiRF's high-sensitivity software like SiRFXtrac and SiRFLoc. With a cold start time under 45 seconds and low power consumption (under 175 mW at full power, reducing to under 60 mW in TricklePower mode), the GRF2I is an efficient solution where low power, low cost, and high performance are critical.
