SX7M32.768KM20F30TNN有源晶振产品概述
一、产品定位与核心应用场景
SX7M32.768KM20F30TNN是星通时频（SCTF）推出的低功耗高精度32.768kHz有源晶振，针对电池供电设备、宽温环境下的时钟基准需求定向设计，核心应用覆盖三大领域：
- 便携消费电子：智能手环、智能手表、蓝牙耳机等设备的实时时钟（RTC）模块，低功耗特性延长电池续航；
- 物联网（IoT）节点：传感器节点、LPWAN（LoRa/NB-IoT）设备的时钟同步基准，宽温范围适配户外/工业环境；
- 工业与车载电子：PLC、工业传感器、车载胎压监测等系统的辅助时钟，稳定度满足长期可靠运行需求。
二、关键性能参数解析
该晶振的核心参数围绕高精度、低功耗、宽适配三大核心设计，具体解析如下：
1. 频率精度与稳定度
- 常温频差±20ppm：在25℃环境下，频率偏差控制在32.768kHz×20×10⁻⁶=0.655Hz内，满足RTC模块日常时间精度需求；
- 全温频率稳定度±30ppm：在-40℃~+85℃宽温范围内，频率漂移≤0.983Hz，每日时间误差约2.6秒，优于多数石英表计时精度。
2. 输出与电气兼容性
- CMOS输出：电平兼容1.8V/3.3V数字电路，无需额外电平转换芯片，简化系统设计；
- 宽电压范围：1.62V~3.63V供电，覆盖CR2032纽扣电池（3V）、锂聚合物电池（3.7V）及系统低压场景，适配性强。
3. 低功耗特性
工作电流仅90uA（典型值），搭配CR2032电池时，理论续航可达5年以上（无额外负载），满足长期无人值守设备需求。
三、封装与机械特性
采用SMD7050-4P贴片封装，尺寸约7.0mm×5.0mm×1.5mm，具备三大优势：
- 小型化设计：占用PCB面积小，适配智能穿戴、小型传感器等紧凑设备；
- 自动化贴装：4引脚封装兼容常规SMT生产线，生产效率高、制造成本低；
- 抗干扰性：引脚布局减少电磁干扰（EMI），提升时钟信号稳定性。
四、工作环境适应性
- 宽温范围：-40℃~+85℃覆盖工业现场（户外传感器、车间PLC）、车载环境（低温启动至高温运行）的温度波动；
- 可靠性测试：通过高低温循环、振动（10~2000Hz/1g）、冲击（1000g/0.5ms）等测试，符合工业级环境耐受要求。
五、品牌与可靠性保障
SCTF（星通时频）是国内专注时频元器件的专业厂商，该产品具备以下优势：
- 成熟工艺：采用高精度石英晶体谐振器+有源振荡电路，频率一致性与稳定性经量产验证；
- 环保认证：符合RoHS标准，部分型号可满足AEC-Q100车载级要求；
- 技术支持：提供选型→量产全流程支持，降低客户设计风险。
总结：SX7M32.768KM20F30TNN以低功耗、高精度、宽温适配为核心，是便携电子、物联网、工业控制等领域的高性价比时钟基准选择。
Request for quote

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.
