SI3050-E1-FTR 产品概述
一、核心身份与定位
SI3050-E1-FTR是Skyworks Solutions Inc.推出的电信接口类直接存取装置（DAA）IC，属于SI3050系列的具体型号，专为语音与数据通信系统的线路接口设计。其核心作用是实现模拟电话线路与数字处理单元的信号转换交互，是各类通信终端、网络设备的关键接口组件。该型号采用卷带（TR）包装，目前处于在售状态，适用于量产项目及原型开发。
二、关键参数与性能表现
SI3050-E1-FTR的参数针对通信设备的低功耗、宽适配需求优化，核心性能如下：
- 供电特性：支持3V~3.6V宽电压输入，典型工作电流仅8.5mA，可有效降低设备整体功耗，尤其适合对功耗敏感的便携或嵌入式终端；
- 工作温度：0°C~70°C商业级温度区间，覆盖多数室内通信设备的运行环境，无需额外散热即可稳定工作；
- 通道数量：单通道（1电路）设计，适配单线路通信场景，也可通过并联扩展多线路支持。
三、接口与兼容性优势
该IC配备三种主流通信接口，适配不同系统架构：
- GCI（通用通信接口）：符合电信标准化规范，可直接对接PSTN（公共交换电话网）或企业PBX（专用交换机）线路；
- PCM（脉冲编码调制）：支持8kHz采样率的数字语音传输，与多数语音编码芯片、MCU的PCM接口兼容，实现模拟→数字信号的高效转换；
- SPI（串行外设接口）：高速串行通信接口，便于与MCU/DSP通信，实现参数配置、状态监测，降低系统布线复杂度。
四、封装与安装特性
SI3050-E1-FTR采用20-TSSOP（薄型小尺寸封装），封装宽度仅4.40mm（0.173英寸），体积紧凑，适合空间受限的设备（如桌面电话、语音网关）；表面贴装型安装方式，兼容自动化贴装生产线，提升量产效率；卷带（TR）包装便于批量存储运输，降低物料管理成本。
五、典型应用场景
结合DAA功能与接口特性，该IC广泛应用于：
- 企业通信：企业PBX的模拟线路接口、语音网关的PSTN接入模块；
- 终端设备：数字无绳电话、IP电话的模拟线路适配模块、小型语音交换机；
- 宽带接入：ADSL/VDSL调制解调器的语音接口（实现POTS电话与宽带数据并行传输）；
- 研发原型：通信类项目的快速验证，因在售易采购，适合小批量测试。
六、市场与供货说明
制造商Skyworks是全球射频与通信IC领先厂商，产品以高可靠性、低功耗著称；SI3050-E1-FTR的原厂封装与供应商封装一致（均为20-TSSOP），确保兼容性；目前市场供货稳定，卷带包装支持批量采购，单颗/整盘均可满足项目需求。

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
