SX3M8.000M20F30TNN有源晶振产品概述

一、产品核心定位与典型应用

SX3M8.000M20F30TNN是SCTF星通时频推出的工业级CMOS有源晶振,主打「高精准时钟输出、宽温环境适配、小型化贴片设计」,可满足多场景电子设备的时钟同步需求。其典型应用覆盖:

  • 工业控制:PLC可编程逻辑控制器、工业传感器节点、伺服电机驱动模块(需稳定时钟保证控制精度);
  • 物联网终端:智能网关、环境监测仪、低功耗MCU模块(3.3V电压兼容,3225封装适配紧凑布局);
  • 汽车电子:车载CAN总线模块、仪表盘辅助电路(-40~85℃宽温适配车载高低温环境);
  • 消费电子:智能穿戴(手表/手环)、智能家居控制中心(10mA电流兼顾稳定与低功耗)。

二、关键参数深度解析

1. 频率与精度指标

  • 标称频率:8MHz(主流数字电路常用频率,适配UART、SPI、I2C等总线同步);
  • 常温频差:±20ppm(25℃环境下,误差为±160Hz,满足99%以上数字系统的时钟精度要求);
  • 全温稳定度:±30ppm(-40~85℃范围内,时钟漂移控制在±240Hz内,避免极端温度下系统同步异常)。

2. 电气特性

  • 工作电压:1.62V~3.63V(覆盖1.8V、3.3V主流系统电压,兼容STM32L、ATmega等低功耗MCU);
  • 工作电流:10mA(典型值,兼顾有源晶振的稳定性与功耗平衡,适合电池供电的终端设备);
  • 输出模式:CMOS(输出电平与TTL/CMOS逻辑完全兼容,无需额外驱动电路,直接对接数字芯片时钟输入引脚)。

三、封装与机械特性

采用SMD3225-4P贴片封装,尺寸为3.2mm×2.5mm×0.8mm(长×宽×高),4脚无极性布局:

  • 小型化设计:适配高密度PCB(如穿戴设备的10层板、物联网终端的微型模块);
  • 引脚兼容:符合IPC标准,可直接替换同封装的其他晶振型号(需确认频率/精度匹配)。

四、环境适应性与可靠性

1. 宽温范围

  • 工作温度:-40℃~+85℃(工业级标准,可适应户外传感器、车载舱内等极端环境);
  • 存储温度:-55℃~+125℃(满足运输/长期存储的温度波动要求)。

2. 抗干扰与可靠性

  • 有源内置振荡电路:相比无源晶振,抗电磁干扰能力提升30%以上(适合工业现场、车载电磁复杂环境);
  • 环保与寿命:符合RoHS无铅标准,典型MTBF(平均无故障时间)≥10万小时,批量一致性误差≤±5ppm。

五、品牌与品质保障

SCTF星通时频是国内专注时频器件研发的高新技术企业,产品通过ISO9001质量管理体系认证,部分型号符合AEC-Q200汽车级标准:

  • 测试环节:SX3M8.000M20F30TNN经过「高低温循环测试(100次)、振动测试(10G/20~2000Hz)、老化测试(72小时)」,确保批量稳定性;
  • 应用验证:已批量应用于国内某工业PLC厂商、某智能穿戴品牌的终端产品,市场反馈故障率≤0.1%。

六、选型与应用注意事项

  1. 电压匹配:确认目标电路电压在1.62V~3.63V内,避免过压(>3.63V可能损坏)或欠压(<1.62V无法启动);
  2. 焊接工艺:推荐回流焊(峰值温度≤260℃,时间≤10秒),禁止手工焊接时烙铁直接接触晶振本体;
  3. 负载设计:CMOS输出无需负载电容,直接连接MCU时钟输入引脚(无需像无源晶振配置22pF匹配电容);
  4. 布局建议:晶振靠近MCU时钟引脚,减少走线长度(≤5cm),避免与高频信号线并行(降低干扰)。

该产品凭借精准的时钟输出、宽温适应性与小型化设计,成为工业控制、物联网、汽车电子等领域的高性价比选择,可直接替换同类进口晶振(如EPSON、NDK的同规格型号)。

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
