SX3M19.200M20F30TNN 有源晶振产品概述

SX3M19.200M20F30TNN是星通时频(SCTF) 推出的一款工业级CMOS有源晶振,以19.2MHz为核心频率,兼顾宽电压适配、全温稳定性与小型化封装,可满足消费电子、工业控制、物联网等多领域的时钟信号同步需求,是主流电子系统的可靠时钟基准器件。

一、产品基本定位与核心属性

该晶振属于有源石英晶振(内置振荡电路,无需外部匹配元件即可输出稳定时钟),核心定位为“通用型高频时钟器件”:

  • 采用CMOS输出模式,信号完整性好,可直接驱动数字电路(如MCU、FPGA);
  • 封装为SMD3225-4P(3.2mm×2.5mm贴片封装),适配自动化贴装,节省PCB空间;
  • 19.2MHz是工业与消费领域的标准化频率,与多数MCU(如STM32系列)、通信模块(蓝牙/ WiFi)的时钟需求高度匹配,减少设计适配成本。

二、核心性能参数深度解析

1. 频率与稳定度

  • 核心频率:19.2MHz(±0Hz标称,无额外偏移);
  • 常温频差:±20ppm(即19.2MHz×20ppm=384Hz),满足普通电子系统的时钟精度要求(如音频解码、UART通信);
  • 全温稳定度:±30ppm(-40℃~+85℃范围内),即576Hz偏移量,工业环境下仍能保持时钟信号稳定,避免温度变化导致的设备误动作。

2. 电气特性

  • 工作电压:1.62V~3.63V(覆盖1.8V、3.3V主流供电),适配低功耗设备(如智能手环1.8V)与普通电子设备(3.3V);
  • 工作电流:10mA(典型值),兼顾输出驱动能力与功耗控制,适合电池供电设备的长期使用;
  • 输出模式:CMOS(高电平≈Vcc,低电平≈GND),信号幅度大、噪声低,无需额外电平转换电路,简化系统设计。

3. 环境适应性

  • 工作温度:-40℃~+85℃(工业级温度范围),可在低温户外(如北方冬季)、高温车间等场景稳定工作;
  • 存储温度:-55℃~+125℃(超出工作温度范围,确保运输/存储安全)。

三、封装与物理特性

采用SMD3225-4P标准贴片封装,具体参数:

  • 尺寸:3.2mm(长)×2.5mm(宽)×1.0mm(高),属于小型化晶振,适合智能穿戴、物联网终端等对体积敏感的设备;
  • 引脚定义:4引脚(2个电源脚、2个输出脚),符合行业通用晶振引脚布局,替换方便;
  • 贴装兼容性:支持SMT自动化贴装,适配回流焊工艺,生产效率高。

四、典型应用场景

1. 消费电子领域

  • 智能手表、蓝牙耳机、便携式音箱:小型化封装适配穿戴设备体积,1.62V低电压适配电池供电,19.2MHz作为MCU时钟基准,满足音频解码、蓝牙通信需求;
  • 智能家居终端(如智能音箱):稳定的时钟信号确保语音识别、WiFi连接的准确性。

2. 工业控制领域

  • PLC(可编程逻辑控制器)、工业传感器节点:-40℃~+85℃工作温度覆盖车间/户外环境,±30ppm稳定度避免设备误触发;
  • 电机控制器:19.2MHz时钟满足PWM调速的精度要求。

3. 物联网终端

  • 智能电表、环境监测传感器:1.62V低电压适配电池供电,10mA工作电流延长电池寿命,19.2MHz作为LoRa/WiFi模块的时钟基准;
  • 农业物联网节点:全温范围稳定工作,适应田间高低温环境。

4. 通信模块

  • 蓝牙4.0/5.0模块、NB-IoT模块:19.2MHz是模块内部电路的常用时钟频率,减少时钟同步误差,提升通信稳定性。

五、品牌与可靠性优势

星通时频(SCTF)是国内专注频率控制元器件的高新技术企业,拥有10余年晶振研发生产经验,产品优势:

  • 可靠性认证:通过ISO9001质量体系、RoHS环保认证,经过高低温循环(100次)、振动(10~2000Hz/1g)、冲击(1000g/1ms)等测试,确保长期稳定;
  • 供货稳定:具备批量生产能力,供货周期短,适合工业级客户批量采购;
  • 性价比突出:在同类工业级晶振中,平衡了性能与成本,适合中低端电子设备的成本控制需求。

总结

SX3M19.200M20F30TNN有源晶振凭借宽电压适配、全温稳定、小型化封装与CMOS输出优势,成为多领域时钟同步的优选器件,可覆盖消费电子、工业控制、物联网等场景的多样化需求,是电子系统设计中可靠的时钟基准选择。

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
