SX3M8.000B10G40TNN有源晶振产品概述

一、产品定位与品牌依托

SX3M8.000B10G40TNN是星通时频(SCTF) 推出的工业级有源晶振,核心用于为电子设备提供精准、稳定的8MHz时钟基准信号,针对对宽温适应性、频率稳定度有要求的场景设计。SCTF作为国内专业时频元器件供应商,其产品覆盖工业控制、通信、物联网等领域,该型号延续了品牌在宽温晶振上的成熟技术,兼顾性能与成本优势,适合批量应用。

二、核心性能参数深度解析

1. 频率与稳定度特性

  • 基准频率:8MHz,是工业控制、数字电路中常用的中低频时钟,适配多数MCU、FPGA的时钟输入范围,无需额外分频/倍频;
  • 常温频差:±10ppm,即25℃环境下,输出频率偏差不超过80Hz(计算:(8×10^6\ \text{Hz}×10×10^{-6}=80\ \text{Hz})),精度满足常规数字系统的时钟同步需求;
  • 频率稳定度:±40ppm(全温区),涵盖-40℃~+105℃极端温度范围,意味着低温启动或高温工作时,频率偏差仍控制在320Hz以内,远优于普通商业级晶振(通常±50ppm以上),保障设备长期可靠运行。

2. 电气与输出特性

  • 工作电压:3.3V单电源供电,为当前电子设备主流规格,无需电平转换电路,兼容性强;
  • 工作电流:10mA(典型值),在有源晶振中属于适中水平,兼顾时钟稳定性与系统功耗控制,适合对功耗敏感但需稳定时钟的设备;
  • 输出模式:CMOS电平输出,高电平接近3.3V、低电平接近0V,直接匹配多数数字芯片的输入逻辑,无需缓冲放大,简化电路设计。

3. 环境与封装特性

  • 工作温度范围:-40℃~+105℃,符合工业级宽温标准,可满足户外设备、车载电子、工业自动化等极端场景需求;
  • 封装形式:SMD3225-4P(贴片式),尺寸约3.2mm×2.5mm×1.0mm,体积小巧,适配小型化、高密度PCB设计;4引脚布局支持自动化贴片生产,焊接可靠性高,抗振动性能优于插件封装。

三、典型应用场景

SX3M8.000B10G40TNN的宽温稳定性与CMOS输出特性,使其适用于以下场景:

  1. 工业自动化设备:PLC、传感器模块、工业机器人控制器,需在-20℃~+60℃甚至更宽温度下稳定工作;
  2. 通信与物联网终端:小型基站、无线AP、智能电表、环境监测节点,需精准时钟同步且对体积敏感;
  3. 车载电子系统:车载信息娱乐系统、ADAS辅助驾驶模块,满足-40℃低温启动与+85℃高温工作要求;
  4. 消费电子与医疗设备:智能穿戴、便携式医疗仪器,兼顾小型化与宽温适应性。

四、产品优势总结

  1. 宽温可靠:全温区±40ppm稳定度,解决极端环境下时钟漂移问题;
  2. 高兼容性:3.3V CMOS输出,直接匹配主流数字芯片,简化电路;
  3. 小型化设计:SMD3225封装节省PCB空间,适配高密度产品;
  4. 品牌保障:SCTF成熟工艺,产品一致性好,批量应用可靠性高。

该型号为工业级应用提供了高性价比的时钟解决方案,可满足多数中低频数字系统的时钟需求。

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
