The NaviLink single-chip solution is manufactured in 90nm process technology and extends TI's leadership in single-chip integrated solutions using TI's DRP™ technology. Through DRP technology, TI is able to provide the smallest size and lowest cost GPS discrete solution with low power and high performance to mobile phone manufacturers.
- Smallest size: The GPS5300 NaviLink 4.0 solution integrates a complete GPS system into one chip, significantly reducing the board layout area for a discrete GPS engine. The single-chip enables a board area for the complete system of less than 50 mm2.
- Lowest cost: As a single chip, the GPS5300 only requires 11 external passives, a significant reduction over existing solutions which require up to 30 external passives. This level of integration delivers a total bill of materials that is almost 50 percent less than competition today.
- Low Power: The GPS5300 NaviLink 4.0 solution has power management integrated on-chip, which simplifies design and further reduces the bill-of-materials. The single chip also allows direct connect to battery for easy incorporation into mobile phone designs.
- High performance: The GPS5300 NaviLink 4.0 solution enables a rapid time to first fix (TTFF) from weak satellite signals, exceeding the GPS requirements for 3GPP and 3GPP2 operation.
