SX3M25.000B10F20TNN有源晶振产品概述

SX3M25.000B10F20TNN是星通时频(SCTF)推出的一款工业级CMOS输出有源晶振,针对中高精度频率基准需求设计,具备宽温适应性、强电平兼容性、小型化封装等特点,广泛适配工业控制、物联网终端等场景。

一、产品核心定位与优势

该晶振聚焦工业级频率基准需求,核心优势体现在三方面:

  1. 电平匹配友好:采用CMOS输出模式,高电平接近3.3V工作电压,低电平接近0V,可直接对接多数3.3V数字电路(如MCU、FPGA),无需额外电平转换;
  2. 宽温稳定可靠:工作温度覆盖-40℃~+85℃,频率稳定度控制在±20ppm以内,满足户外、车间等复杂环境下的长期稳定运行;
  3. 小型化适配性:SMD3225-4P封装(3.2mm×2.5mm常规尺寸),适配高密度PCB布局,符合终端产品小型化趋势。

二、关键参数详细解析

1. 频率与精度指标

  • 标称频率:25MHz(常用基准频率,适配多数MCU、通信模块的时钟需求,无需额外分频/倍频);
  • 常温频差:±10ppm(换算为250Hz,即常温下频率偏差不超过±250Hz,满足一般工业设备、消费电子的精度要求);
  • 频率稳定度:±20ppm(指-40℃~+85℃范围内,频率相对于常温的最大变化量,比同价位无源晶振稳定度高2-3倍,体现温区适应性)。

2. 电气性能

  • 工作电压:3.3V(主流数字电路供电电压,无需升压/降压转换,直接匹配系统电源);
  • 工作电流:10mA(有源晶振常规电流范围,兼顾稳定性与功耗平衡,适合电池供电的物联网终端);
  • 输出模式:CMOS(推挽输出,驱动能力较强,可直接驱动2-3个数字负载,无需额外缓冲)。

3. 封装与机械特性

  • 封装类型:SMD3225-4P(表面贴装4引脚,引脚间距常规,焊接工艺成熟,适合自动化生产);
  • 尺寸:3.2mm×2.5mm(长度×宽度,高度约1.0mm,具体以厂商datasheet为准);
  • 引脚定义:通常为2脚(Vcc)、4脚(GND)、1/3脚(输出),需参考官方手册确认焊接顺序。

三、典型应用场景

SX3M25.000B10F20TNN的参数特性决定了其适用于以下场景:

  1. 工业控制设备:PLC(可编程逻辑控制器)、传感器节点、工业机器人的时钟基准,宽温适应车间/户外环境;
  2. 物联网终端:智能电表、环境监测仪、无线网关的MCU时钟,小型化封装适配终端紧凑设计;
  3. 通信模块:2G/4G模块、蓝牙模块的参考时钟,25MHz是多数通信芯片的常用基准频率;
  4. 消费电子:智能家居设备(如智能音箱、安防摄像头)的时钟源,满足3.3V系统供电需求。

四、可靠性与选型注意事项

1. 可靠性说明

  • 采用石英晶体作为振荡元件,老化率低(长期使用频率漂移小,适合长期运行设备);
  • SMD贴片封装焊接可靠性高,抗振动、抗冲击性能优于插件封装,适应运输与现场振动环境;
  • 星通时频(SCTF)作为国内晶振领域主流厂商,产品经过批量验证,适合量产需求。

2. 选型注意事项

  • 电压匹配:确认系统供电为3.3V,避免5V供电导致芯片损坏;
  • 负载兼容性:CMOS输出可直接驱动数字负载,若需驱动模拟电路需增加缓冲器;
  • 精度升级:若系统需更高精度(如±5ppm以内),需选择SCTF对应高精度型号;
  • 温区扩展:若使用环境温度超出-40℃+85℃(如汽车级-40℃+125℃),需更换汽车级晶振型号。

该晶振以平衡的性能与成本,成为工业、物联网领域中高精度频率基准的实用选择,适合对尺寸、温区、电平兼容性有要求的终端设计。

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.

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.

Replenishment inquiry Typical RFQ workflow
