The document introduces the reference design of GPS module, including module features, design principles, performance testing, layout recommendations, etc.
This document provides a reference design for integrating a Motorola GPS receiver module into a device. It explains the module’s features, hardware layout, and connection options, and includes guidelines for RF design, power supply, and antenna integration.
The guide covers board operation, performance testing using the SiRFOncore application, Java‑based control via the G24 module, and detailed layout recommendations such as 50 Ω trace matching, ground plane requirements, and bypass capacitor placement.
