SX5M4.096M20F30TNN 有源晶振产品概述

这款由星通时频(SCTF)推出的SX5M4.096M20F30TNN有源晶振,是针对工业级、通信及嵌入式系统设计的高精度时钟基准器件,凭借精准的频率标定、宽温宽电压适配性,成为多场景下可靠的时钟解决方案。

一、核心参数精准标定

作为有源晶振,其核心参数经过严格校准,关键指标清晰可查:

  • 频率基准:4.096MHz(行业常用高精度时钟值,适配多数通信与计时场景);
  • 精度范围:常温频差±20ppm(25℃环境下频率偏差极小,满足基础精度需求),全温范围(-40℃~+85℃)频率稳定度±30ppm(宽温下仍保持稳定);
  • 电气特性:工作电压1.62V~3.63V(覆盖低功耗MCU到通用3.3V系统),工作电流10mA(平衡性能与功耗,避免过度耗电);
  • 输出模式:CMOS电平输出(无需电平转换,直接对接主流数字芯片);
  • 封装与温宽:SMD5032-4P贴片封装(5.0×3.2×1.0mm),工作温度-40℃~+85℃(工业级温宽,适配极端环境)。

二、关键性能设计亮点

相比普通消费级晶振,SX5M4.096M20F30TNN在性能上针对工业场景做了优化:

  1. 宽电压适配性:1.62V的低电压支持让它能适配低功耗设备(如智能手表、便携式医疗仪器),3.63V的上限又能兼容车载、工业控制等3.3V系统,无需额外电源转换电路;
  2. 全温稳定表现:-40℃~+85℃的温宽覆盖了多数户外、车载、工业现场的温度变化,±30ppm的稳定度确保时钟不会因温差出现明显偏差,避免设备通信、计时出错;
  3. CMOS输出兼容性:输出电平与主流单片机(如STM32、ATmega)、FPGA、DSP等数字芯片的IO口完全匹配,直接连接即可使用,减少BOM成本与电路复杂度;
  4. 常用频率价值:4.096MHz是UART波特率(9600bps、115200bps)、SPI时钟分频(如12MHz分频至4.096MHz)、高精度计时(1ms=4096个时钟周期)的理想基准,无需复杂分频电路即可匹配多数协议。

三、封装与物理特性

采用SMD5032-4P贴片封装,具有以下物理优势:

  • 小型化设计:5.0×3.2×1.0mm的尺寸适合现代电子设备的小型化趋势,如智能穿戴、微型传感器节点;
  • 自动化贴装:4引脚布局符合SMT工艺要求,可通过自动化贴片机快速焊接,提高生产效率;
  • 环保与可靠性:符合RoHS无铅无卤标准,焊接可靠性高(回流焊峰值温度≤260℃),抗机械振动能力较强(内部振荡器封装紧凑,振动对频率影响小)。

四、典型应用场景匹配

SX5M4.096M20F30TNN的参数特性使其适配多个领域:

  1. 工业控制模块:PLC、工业传感器、数据采集卡等,宽温宽电压满足工业现场的复杂环境;
  2. 通信设备:低功耗蓝牙模块、LoRa网关、UART通信接口,4.096MHz精准生成波特率;
  3. 车载电子:车载显示屏、胎压监测模块、ADAS辅助系统,-40℃~+85℃温宽适配车载高低温环境;
  4. 消费电子高端款:智能手表、运动手环(低电压适配)、便携式血糖仪(高精度计时);
  5. 嵌入式开发:单片机最小系统、FPGA开发板、物联网节点,CMOS输出简化电路设计。

五、选型与使用注意事项

为保证性能稳定,使用时需注意:

  1. 电源滤波:电源引脚并联0.1μF陶瓷电容,滤除高频噪声,避免时钟抖动;
  2. 负载控制:输出端寄生电容不超过15pF(避免过长走线或过多负载),否则可能影响频率精度;
  3. 焊接规范:回流焊温度≤260℃,手工焊接时间≤3秒(温度≤350℃),防止内部振荡器损坏;
  4. 静电防护:有源晶振对静电敏感,存储/焊接时需使用防静电袋、接地工作台,避免静电击穿。

总结来看,SX5M4.096M20F30TNN有源晶振凭借精准的参数、工业级的稳定性能、广泛的兼容性,成为工业控制、通信、车载等领域的可靠时钟选择,其小型化封装也适配现代电子设备的发展需求。

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.
