LocSense Technology, Inc., a GPS module and IC solution provider, has announced its LS4000 Correlation Engine which delivers a high level of performance with low power consumption and low cost. It is targeted at mobile computing platforms, such as PDAs, tablet-PCs and smart-phones requiring GPS-navigation or GPS-tracking functions.
With rapid time-to-first-fix and enhanced sensitivity, the LS4000 is designed to meet rising expectations of GPS performance on the fast growing range of GPS applications. With massive parallel hardware, the chip features 4000 time/frequency search bins, allowing acquisition of all visible satellites within 2 seconds for warm-start, and less than 10 seconds for cold-start. Sensitivity is better than -140dBm for unaided signal acquisitions, and better than -147dBm for tracking GPS signals.
The small LS4000 tracks GPS signals, and generates GPS measure-ments. Together with sharing host processor and memory resource, it reduces system cost by adding GPS functionality onto a mobile computing platform.
The LS4000 is packaged in TQFP-64 that supports 16-bit data bus interface compatible with most 16/32-bit processors. With a supply voltage of 3.3V, peak current during signal acquisition is between 38 and 15mA for all 12 channels in continuous tracking mode; current consumption is lowered by turning-off the unused channels.
