Confidential / Released 6 / 45 GNSS Module L76 Hardware Design 1 Introduction This document defines and specifies L76 GNSS module. It describes L76 GNSS module hardware interface and its external application reference circuits, mechanical size and air interface. This document can help you quickly understand the interface specifications, electrical and mechanical details of L76 GNSS module. We also offer you other documents such as L76 software application notes and user guider. These documents can ensure you use L76 module to design and set up mobile applications quickly. l e t l c a i e t u n Q fide n o C L76_Hardware_Design Downloaded from Arrow.com. Confidential / Released 7 / 45 GNSS Module L76 Hardware Design 2 Product Concept 2.1. General Description L76 is a single receiver module integrated with GLONASS and GPS system. It is able to achieve the industry’s highest level of sensitivity, accuracy and TTFF with the lowest power consumption in a small-footprint lead-free package. The embedded flash memory provides capacity for storing user-specific configurations and allows for future updates. l e t l c a i e t u n Q fide n o C The L76 GNSS module supports multiple positions and navigation system including autonomous GPS, GLONASS, SBAS (including WAAS, EGNOS, MSAS and GAGAN), QZSS, and AGPS. Embedded with many advanced power saving modes including period, AlwaysLocateTM, standby and backup, L76 GNSS module has excellent low-power consumption in different scenes. EASY technology as the key feature of L76 is one kind of AGPS. Collecting and processing all internal aiding information like GPS time, Ephemeris, Last Position etc, the GNSS module will have a fast TTFF in either Hot or Warm start. L76 GNSS module is an SMD type module with the compact 10.1mm x 9.7mm x 2.5mm form factor, which can be embedded in your applications through the 18-pin pads. It provides necessary hardware interfaces between the module and your board. The module is fully ROHS compliant to EU regulation. L76_Hardware_Design Downloaded from Arrow.com.
