该产品属于HCI TC系列振荡器,聚焦中高精度时钟基准需求,针对工业控制、通信、消费电子等领域设计——既具备工业级环境耐受能力,又兼顾消费电子的成本与封装紧凑性要求,是替代传统陶瓷谐振器、提升系统时钟精度的优选方案。

二、关键性能参数详解

1. 频率特性

  • 标称频率:25MHz(通信与数字系统常用中频,兼容性强);
  • 频率稳定度:±1ppm(-40℃~+85℃范围内,频率偏差≤25Hz,满足数据同步、微处理器时序控制等需求);
  • 频率老化率:HCI工艺保证长期稳定性(典型值≤±1ppm/年)。

2. 输出特性

  • 输出模式:CMOS逻辑电平(高电平≥3.3V-0.5V,低电平≤0.5V),与3.3V TTL/CMOS电路无缝兼容,无需电平转换;
  • 输出负载:典型15pF,高扇出能力(可驱动8个以上数字器件)。

3. 电源特性

  • 工作电压:3.3V单电源供电(主流数字系统电压,简化电源设计);
  • 静态功耗:典型≤5mA,适合电池供电或低功耗场景。

三、封装与电气特性适配

1. 封装规格

  • 封装类型:SMD3225-4P(表面贴装,3.2mm×2.5mm×0.8mm厚度);
  • 引脚配置:标准4引脚(Vcc、GND、OUT、可选EN使能),适配常规PCB布局,支持回流焊(温度曲线符合IPC标准)。

2. 电气兼容性

  • 输出电平与3.3V系统完全匹配,避免信号失真;
  • 输入阻抗≥10kΩ,抗电源纹波能力强,减少噪声干扰。

四、工作环境与可靠性说明

1. 温度适应性

  • 工作温度:-40℃~+85℃(工业级范围,覆盖户外设备、工业现场、车载后装等场景);
  • 温度系数:≤±0.5ppm/℃,温度变化下频率漂移极小。

2. 可靠性与环保

  • 符合RoHS2.0无铅无卤标准,适合出口产品;
  • 抗振动/冲击:满足IEC 60068-2-6(振动)、IEC 60068-2-27(冲击)测试要求;
  • 长期可靠性:MTBF≥10^6小时,适合7×24小时运行的工业设备。

五、典型应用场景

该产品因参数适配性强,广泛应用于:

  1. 工业控制:PLC、变频器、伺服驱动器(稳定时钟保证控制时序);
  2. 通信设备:小型基站、无线AP、路由器(25MHz用于中频处理);
  3. 消费电子:机顶盒、智能电视、游戏机(3.3V CMOS适配主控芯片);
  4. 汽车电子:车载导航、行车记录仪(-40~85℃适配车载环境);
  5. 医疗设备:监护仪、血糖仪(高精度时钟保证数据同步)。

六、产品优势总结

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
