SI4739規(guī)格書詳情
Introduction
This document provides general Si47xx design guidelines and AM/FM/SW/LW/WB antenna selections which includes schematic, BOM, layout and design checklist. All users should follow the Si47xx design guidelines presented in Section 2 and then users can proceed to the appropriate antenna selections according to the application and device used presented in Sections 3 through 10. To get an in-depth knowledge about each individual antenna, the antenna theory and interface model is presented in the Appendices
Si47xx 3x3 mm QFN Schematic and Layout
This section shows the minimal schematic and layout options required for optimal Si47xx performance. Population options are provided to support a single layout for all 3 x 3 mm QFN devices, mitigate system noise, operate the internal oscillator with an external crystal, and filter VCO energy.
