GSD4E-9333-TR

SiRFstarIV™ GSD4e Description SiRFstarIV™ GSD4e WLCSP is a complete navigation processor built on a low-power RF CMOS single-die, incorporating the baseband, integrated navigation solution, software, ARM7 processor, and RF functions that form a complete internal ROM-based standalone or Aided-GPS engine. GSD4e WLCSP is based on the new SiRFstarIV architecture. GSD4e WLCSP lowers BOM costs and risk while delivering industry-leading GPS performance in a compact solution. GSD4e WLCSP serves the traditional GPS engine market because it can generate a PVT solution without relying upon host device processing power or other resources. Key Features High performance solution Adaptive micropower controller Active jammer remover Advanced navigation features Tiny solution size Simple to use Watch the latest video demo on: GPS Watches Benefits SiRFaware™ technology means never having to maintain full power to achieve maximum performance, nor turning the GPS receiver completely off to save power. It breaks the old GPS performance vs power trade-off through the fusion of a new high-performance GPS engine, advanced power management, and a smart sensor interface to achieve high sensitivity hot-start conditions for fast location fixes while drawing only 50-400 μA. Premium on-chip software provides a new level of continuous location awareness by employing the following advanced technology: Opportunistic ephemeris decode and advanced power management allow the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power Local ephemeris prediction, capturing ephemerides, and predicting them three days to one week in advance boosts sensitivity and performance Dynamic contextual awareness, temperature monitoring, and MEMS sensors work in concert to conserve power and boost performance The GSD4e serves the traditional GPS engine market by generating a PVT solution via its 109 MHz ARM7 CPU without relying on host processing power or other resources. The on-chip processor also allows customers to differentiate their products. High Performance Solution High sensitivity navigation engine (PVT) tracks as low as -163dBm 48 track verification channels SBAS (WAAS or EGNOS) Adaptive Micropower Controller Only 50 to 500μA maintains hot start capability
