SX3M2.4576M20F30TNN 温补晶体振荡器产品概述

一、产品定位与核心优势

SX3M2.4576M20F30TNN是星通时频(SCTF)推出的工业级温补晶体振荡器(TCXO),针对中精度时钟同步需求设计,兼顾小型化、宽电压兼容与温度稳定性。核心优势包括:2.4576MHz标准时钟频率、±30ppm全温频率稳定度、1.62V~3.63V宽供电范围、SMD3225-4P超小封装,可广泛适配物联网、工业控制、消费电子等场景。

二、关键参数深度解析

  1. 频率与频差
    标准输出频率为2.4576MHz,是通信领域(如蓝牙、ZigBee)与微控制器(MCU)的常用时钟频率。常温(25℃)下频差≤±20ppm,即频率偏差不超过49.15Hz;全工作温度范围(-40℃~+85℃)内稳定度≤±30ppm,偏差≤73.73Hz,可有效避免温度变化导致的时钟漂移,满足大多数中精度场景需求。

  2. 电气特性

    • 输出模式:CMOS数字电平,高电平≥0.8×VDD,低电平≤0.2×VDD,无需电平转换即可直接驱动主流MCU、通信模块;
    • 工作电压:1.62V~3.63V,覆盖1.8V、3.3V等主流供电,兼容低功耗物联网设备与常规工业模块;
    • 工作电流:典型值10mA,在温补晶振中属于中等功耗,平衡稳定性与能效,适合电池供电的便携设备。
  3. 环境适应性
    工作温度范围-40℃+85℃,达到工业级标准,可在户外低温(如北方冬季)、车间高温(如注塑车间)环境稳定运行;存储温度-55℃+125℃,湿度≤85%RH,长期存储无性能衰减。

三、封装与贴装兼容性

采用SMD3225-4P贴片封装,具体尺寸为3.2mm(长)×2.5mm(宽)×1.0mm(高),引脚间距0.8mm,符合IPC标准。该封装支持回流焊、波峰焊工艺,贴装效率高,适合自动化生产;同时超小体积可显著降低PCB空间占用,适配智能穿戴、小型传感器等便携设备(如智能手表的蓝牙模块)。

四、典型应用场景

  1. 物联网终端:蓝牙BLE模块、ZigBee节点的时钟参考,保证设备间通信同步(如智能家居的温湿度传感器);
  2. 工业控制:PLC模块、工业传感器的外部时钟源,适应-40℃~+85℃的工业环境(如工厂生产线的温度监测节点);
  3. 消费电子:智能手表、智能家居网关的时钟模块,小型化封装匹配便携设计(如儿童智能手表的定位模块);
  4. MCU时钟:STM32、AVR等微控制器的外部晶振替代方案,提高时钟稳定性(优于无源晶振,减少误码率);
  5. 通信接口:UART、SPI串口通信的时钟基准,避免数据传输误码(如工业串口屏的通信模块)。

五、可靠性验证

该产品经过严格可靠性测试,确保长期稳定运行:

  • 振动测试:10g~2000Hz扫频,无频率偏移超标;
  • 冲击测试:1000g/0.5ms,性能无衰减;
  • 老化测试:1000小时高温老化(85℃),频率稳定度仍保持±30ppm以内;
  • 湿度测试:85%RH/85℃环境下1000小时,无引脚氧化或性能下降。

综上,SX3M2.4576M20F30TNN是一款高性价比的工业级温补晶振,可满足中精度时钟需求的多场景应用,尤其适合对温度稳定性、小型化有要求的设备设计。

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
