SX3M100.000B20F30TNN 产品概述

一、产品基本定位与核心属性

SX3M100.000B20F30TNN是SCTF(星通时频) 推出的工业级贴片有源晶振,属于3.3V CMOS输出系列,专为中高频稳定时钟信号场景设计。其采用紧凑的SMD3225-4P封装(3.2×2.5mm尺寸、4引脚),适配小型化电子设备的集成需求,核心频率为100MHz,是工业控制、通信、消费电子等领域的通用时钟源解决方案。

二、关键性能参数解析

该晶振针对稳定性与精度做了针对性优化,核心指标覆盖实际应用的核心需求:

  1. 频率精度:常温(25℃)频差为±20ppm,即100MHz信号的频率偏差范围为±2kHz(100MHz×20×10⁻⁶),满足大多数数字电路对时钟精度的基本要求;
  2. 温度稳定度:全工作温度范围(-40℃~+85℃)内的频率稳定度为±30ppm,温度变化导致的频率偏移最大不超过±3kHz,保障极端环境下时钟信号的可靠性;
  3. 输出特性:采用CMOS输出模式,输出电平与3.3V逻辑系统完全兼容,可直接驱动MCU、FPGA、通信芯片等数字电路,无需额外电平转换;
  4. 功耗特性:工作电流典型值为40mA,3.3V供电下功率约0.132W,兼顾性能与低功耗需求,适合电池供电或功耗敏感设备。

三、电气与环境适应性

3.1 电气特性

  • 工作电压:支持3.3V±5%范围,兼容工业与消费电子常见电源;
  • 输出负载:CMOS输出适配15pF30pF负载电容(需根据电路实际匹配),输出上升/下降时间(10%90%)典型值≤10ns,确保时钟信号完整性;
  • 启动时间:典型启动时间≤10ms,满足实时控制系统等快速上电需求。

3.2 环境适应性

  • 工作温度:-40℃~+85℃(工业级宽温),可适应户外、车载、工业现场等极端环境;
  • 存储温度:-55℃~+125℃,延长产品存储周期与可靠性;
  • 抗振性能:SMD封装具备良好抗振性,可承受10g20g(102000Hz)振动,适合移动设备或工业设备的振动场景。

四、封装与典型应用场景

4.1 封装细节

采用SMD3225-4P 贴片封装,尺寸为3.2mm(长)×2.5mm(宽)×1.0mm(高),4引脚布局符合标准贴片晶振定义(通常为:1-输出、2-接地、3-电源、4-接地/使能,需参考 datasheet 确认),支持回流焊工艺,适配自动化贴装生产线。

4.2 典型应用

  1. 工业控制:PLC、伺服驱动器、传感器模块等,需稳定时钟保障控制精度;
  2. 通信设备:路由器、交换机、无线AP等,100MHz是数据传输与处理的核心频率;
  3. 消费电子:智能终端、机顶盒、游戏机等,兼顾性能与小型化需求;
  4. 车载电子:车载导航、ADAS系统等,适应宽温与振动环境。

五、选型价值与注意事项

5.1 选型优势

  • 性价比平衡:工业级性能(宽温、稳定度)与通用型价格匹配,适合中低端到中端设备;
  • 兼容性强:3.3V CMOS输出直接对接主流数字芯片,减少外围电路;
  • 小型化设计:SMD3225封装节省PCB空间,适配高密度集成设备。

5.2 注意事项

  • 负载匹配:需根据电路实际负载电容(15pF~30pF)选择匹配电容,避免频率偏移;
  • 电源滤波:建议在电源引脚增加0.1μF陶瓷电容滤波,减少电源噪声干扰;
  • 焊接工艺:回流焊峰值温度需≤260℃、时间≤10s,避免损坏晶振内部结构。

六、总结

SX3M100.000B20F30TNN作为SCTF的主流有源晶振产品,以100MHz核心频率、工业级宽温、CMOS输出、紧凑封装 为核心特点,覆盖多领域时钟需求。其平衡的性能与成本,使其成为替代进口同类产品的高性价比选择,适合对时钟稳定性有要求且需控制成本的设备设计。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
