CO75H4-80.000-33JDTSN 产品概述

一、产品定位与核心应用场景

CO75H4-80.000-33JDTSN是杭晶(HCI)推出的工业级3.3V HCMOS输出石英晶振,主打80MHz频率基准,兼顾精度、稳定性与低功耗,适配多类中低频率要求的电子系统。核心应用场景包括:

  1. 工业控制领域:PLC(可编程逻辑控制器)、变频器、伺服驱动器的时钟基准,满足-40~+85℃工业温区需求;
  2. 通信接口设备:以太网交换机(PHY芯片)、RS485/232通信模块的时钟源,HCMOS输出兼容主流通信芯片IO;
  3. 车载电子系统:车载信息娱乐主机、ADAS辅助驾驶单元的MCU时钟,稳定支撑车规级温区工作;
  4. 消费电子与智能家居:机顶盒、路由器、智能网关的无线模块(WiFi/Bluetooth)时钟,低功耗适配电池供电场景。

二、基础电气参数详解

该型号关键电气参数直接决定应用适配性,核心参数及意义如下:

  • 频率:80MHz:主流中高频段,覆盖多数MCU、通信芯片的时钟需求;
  • 常温频差:±10ppm:25℃环境下,频率偏差不超过800Hz(80MHz×10×10⁻⁶),满足一般精度要求(如通信同步、数据传输);
  • 输出模式:HCMOS:兼容3.3V逻辑电平,无需电平转换,可直接驱动MCU、FPGA、PHY等芯片;输出阻抗低(典型<10Ω),信号完整性好;
  • 工作电压:3.3V:主流单电源电压,适配绝大多数嵌入式系统的电源设计,无需额外转换;
  • 工作电流:20mA(典型):低功耗设计,适合电池供电或功耗敏感设备(如智能家居终端);
  • 频率稳定度:±30ppm:全工作温区(-40~+85℃)内,频率总偏差不超过2.4kHz(80MHz×30×10⁻⁶),远优于普通商业级晶振(通常±50ppm),满足工业环境稳定性要求。

三、封装与物理特性

采用SMD7050-4P封装,物理参数如下:

  • 尺寸:7.0mm×5.0mm×1.5mm(典型):贴片式设计,节省PCB空间,适配高密度布局;
  • 引脚数:4引脚:相比2引脚晶振,增加电源(VCC)与地(GND)引脚,增强抗干扰能力,减少外部噪声影响;
  • 表面贴装工艺:适合自动化贴片生产,降低人工成本,提高生产效率;
  • 引脚布局:通常VCC(1脚)、GND(2脚)、输出(3脚)、NC(4脚,可选),需参考HCI官方 datasheet确认具体定义。

四、环境适应性与可靠性

作为工业级晶振,环境适应性是核心优势:

  • 工作温度:-40℃~+85℃:覆盖工业设备典型温区(如户外传感器、工厂控制柜),极端温度下仍保持稳定频率;
  • 储存温度:-55℃~+125℃(HCI标准):满足长期储存温度要求,避免运输/存储损坏;
  • 抗振动性能:10g(5~2000Hz,符合IEC 60068-2-6):可应对工业设备振动环境(如电机、传送带附近);
  • 环保认证:RoHS、REACH:符合欧盟环保要求,无铅无镉,适配绿色产品设计。

五、品牌与选型注意事项

5.1 品牌优势

杭晶(HCI)是国内知名频率器件厂商,专注晶振研发20余年,产品覆盖石英晶振、温补/压控晶振等全系列,经工业、汽车领域多年市场验证,可靠性稳定。

5.2 选型与应用注意

  1. 输出匹配:HCMOS输出无需外接负载电容(内部已做匹配),简化电路设计;
  2. 电源滤波:建议VCC引脚并联0.1μF陶瓷电容(靠近引脚),滤除电源噪声;
  3. PCB布局:
    • 晶振周围避免高频干扰源(如射频电路、开关电源);
    • 电源地(GND)与晶振引脚直接相连,减少走线阻抗;
  4. 温区匹配:若需更高温区(如汽车级125℃),需选择HCI同系列汽车级型号(标注AEC-Q100);
  5. 焊接工艺:采用回流焊(符合J-STD-020标准),避免手工焊接损伤内部结构。

六、总结

CO75H4-80.000-33JDTSN是一款高性价比工业级3.3V HCMOS晶振,以80MHz为核心频率,兼顾精度、稳定性与低功耗,适配工业控制、通信、车载等多场景。杭晶的品牌可靠性与SMD7050封装的易用性,使其成为嵌入式系统时钟基准的优选方案。

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
