TFOM3.579545M4RHKCNT2T 晶体振荡器产品概述

一、产品基本定位

TFOM3.579545M4RHKCNT2T是雅晶鑫(YJX) 推出的一款工业级小封装CMOS晶体振荡器,核心频率为3.579545MHz(经典标准频率),适配3.3V单电源供电,采用SMD3225-4P贴片封装,兼顾小体积、高可靠性与成本效益,主要面向嵌入式系统、工业传感器、视频处理等需要稳定时钟源的场景。

二、核心参数深度解析

该产品的参数设计针对工业级应用需求做了优化,关键指标如下:

1. 频率特性

3.579545MHz是通信、视频领域的成熟标准频率,广泛适配NTSC制式视频同步、低速串口(UART)辅助时钟、MCU外部高速时钟(HSE)等场景,无需额外频率转换即可兼容现有系统。

2. 精度与稳定度

  • 常温频差:±50ppm(实际波动≈±179Hz),满足大多数数字电路对时钟精度的要求(如UART通信要求≤100ppm即可正常传输);
  • 全温稳定度:±50ppm(-40℃~+85℃宽温范围),确保极端环境下频率漂移可控,避免系统同步失效或数据错误。

3. 电气特性

  • 工作电压:3.3V(主流嵌入式系统电压规范,无需电平转换);
  • 工作电流:10mA(稳定振荡所需的合理电流范围,兼顾低功耗与可靠性);
  • 输出模式:CMOS(电平兼容TTL/CMOS逻辑,可直接驱动MCU、FPGA等数字电路)。

4. 封装尺寸

SMD3225-4P(3.2mm×2.5mm×1.2mm),4引脚贴片封装,符合IPC标准引脚间距,适配高密度PCB设计(如智能穿戴、小型传感器模块)。

三、品牌与工艺背景

雅晶鑫(YJX)是国内专注晶体振荡器研发生产的厂商,该产品采用高精度石英晶体谐振器+CMOS振荡电路设计:

  • 谐振器采用特殊切割工艺(如AT切割),控制电极沉积精度,确保频率一致性;
  • 封装采用陶瓷/塑料复合材质,抗机械应力与温度冲击能力强,焊接兼容性好(回流焊/波峰焊均适配)。

四、典型应用场景

结合参数特性,该晶振主要应用于以下领域:

1. 工业传感器模块

  • 温湿度/压力传感器的时钟源(宽温范围适配户外/ harsh环境);
  • 工业物联网(IIoT)终端的辅助时钟(确保数据采集时间戳准确)。

2. 嵌入式系统

  • MCU(如STM32F1/F4系列)的外部高速时钟(HSE),替代内部RC振荡器提升精度;
  • 小型FPGA的参考时钟(满足低速逻辑电路同步需求)。

3. 视频与通信设备

  • 监控摄像头的帧同步时钟(适配部分NTSC制式视频处理);
  • 低功耗蓝牙(BLE)模块的辅助时钟(辅助射频同步);
  • RFID读写器的低频时钟(确保标签识别稳定性)。

4. 消费电子

  • 智能音箱的音频同步时钟(优化音频采样精度);
  • 小型家电控制电路(如洗衣机、空调的时序控制)。

五、产品优势总结

  1. 工业级可靠性:宽温范围(-40~85℃)+全温稳定度±50ppm,适应极端环境;
  2. 小封装高集成:SMD3225体积小,适配高密度PCB设计;
  3. 电气兼容性:3.3V单电源+CMOS输出,无需额外转换电路;
  4. 频率兼容性:经典3.579545MHz,适配多类成熟应用场景;
  5. 成本效益:国产厂商直供,性能稳定同时具备批量成本优势。

六、选型与使用注意事项

  1. 焊接建议:采用回流焊工艺,峰值温度≤260℃,焊接时间≤10s(避免损坏晶体);
  2. 布局优化:晶振电路靠近MCU时钟引脚,减少走线长度(降低电磁干扰);
  3. 负载电容:需配置20pF左右负载电容(参考 datasheet 具体值),确保振荡稳定;
  4. 静电防护:焊接/存储需注意ESD防护(晶体为敏感元件,静电易导致性能失效)。

该产品通过了RoHS认证,符合环保要求,适合批量应用于对时钟精度、可靠性有要求的中低端工业与消费电子场景。

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
