SI4755-A40-GMR是Skyworks推出的集成式AM/FM广播接收器,专为低功耗、小体积的消费电子设备设计,核心定位是替代传统离散元件的广播接收模块,兼具高灵敏度、宽电压兼容与紧凑封装特性,覆盖全球主流广播频段,适合对成本、空间与功耗敏感的便携及车载场景。
内置自动增益控制(AGC)、自动频率控制(AFC),支持单声道/立体声音频输出,无需外部AGC/AFC电路,简化设计复杂度。
采用I2C串行接口,支持标准模式(100kHz)与快速模式(400kHz),仅需2根数据线(SDA、SCL)即可实现控制指令(如选台、音量调节)与状态反馈,大幅减少引脚占用。
核心引脚包含:电源(VDD/VSS)、I2C接口(SDA/SCL)、音频输出(MONO/STEREO)、复位(RST)、中断(INT),功能集成度高,外部仅需少量滤波电容即可工作。
该器件凭借集成度高、性能稳定、成本可控的特点,成为消费电子领域广播接收模块的主流选择之一。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
