OT20164MJBA4SL — YXC扬兴科技 4MHz 贴片有源晶振(SMD2016-4P)

一、产品简介

OT20164MJBA4SL 是扬兴科技(YXC)推出的一款小尺寸贴片有源晶体振荡器,工作频率为 4.000 MHz,标准封装为 SMD2016-4P。该器件集成有源振荡电路,直接输出 CMOS 电平信号,适用于微控制器时钟、低速通信、计时与控制等需要高稳定性时钟源的应用场景。器件支持 1.8V 至 3.3V 宽电源电压,工作温度范围为 -40℃ 至 +85℃,满足工业级使用要求。

二、主要性能与特点

  • 频率:4.000 MHz(标称)
  • 常温频差(典型出厂值):±10 ppm
  • 全温区频率稳定度:±20 ppm(含温度影响)
  • 输出模式:CMOS(数字方波,适配 MCU/FPGA/逻辑电平)
  • 工作电压:1.8 V ~ 3.3 V(单电源)
  • 工作温度:-40℃ ~ +85℃
  • 封装:SMD2016-4P(小型贴片封装,适合高密度布局)
  • 品牌:YXC 扬兴科技
  • RoHS 兼容(常见贴片晶振惯例,订购时可确认)

主要优势:

  • 小体积,适合空间受限的便携与模块化设计
  • 宽供电范围,兼容 1.8V 与 3.3V 系统,利于跨平台使用
  • 良好的频率稳定性,满足中高精度时钟需求
  • CMOS 输出直接驱动数字电路,设计实现简单

三、典型应用场景

  • 微控制器(MCU)与数字信号处理器(DSP)时钟源
  • 物联网终端、无线模块、蓝牙/低功耗设备
  • 工业控制与测试设备的低速定时电路
  • RTC 辅助时钟、传感器采样定时
  • 小型通信设备、嵌入式系统开发板与模块化产品

四、封装与安装建议

  • 封装形式:SMD2016-4P(外形尺寸 2.0 mm × 1.6 mm)
  • PCB 布局建议:
    • 在晶振电源端并紧邻放置去耦电容(建议 0.01 μF~0.1 μF),以降低电源噪声对频率稳定性的影响。
    • 信号线尽量短且阻抗控制,避免长信号走线引入干扰。
    • 输出侧如需驱动较大负载,可在设计中考虑缓冲器或适配电路;CMOS 输出适配高阻负载与标准逻辑输入。
  • 回流焊注意事项:遵循厂商提供的回流温度曲线与焊接工艺规范,避免超温或长时间高温影响器件性能与可靠性(订购前建议向厂商获取详细焊接规范)。

五、选型与设计注意点

  • 频率精度要求:本型号常温频差 ±10 ppm,全温稳定度 ±20 ppm。若系统对频率精度要求更高(如 GPS 同步、精密测量),应选择更高稳定度或温补型(TCXO)/原子钟源件。
  • 供电与滤波:在 1.8V 和 3.3V 两档电压间切换时,确认系统逻辑电平兼容,电源去耦要靠近电源引脚以提高抗干扰能力。
  • 老化与长期漂移:晶体振荡器随时间会出现老化影响,长期可靠性设计须预留频差裕量或在系统中采用校准机制。
  • 环境与机械应力:避免强振动与机械应力集中在器件焊点,长期振动会影响晶体稳定性和寿命。

六、检验与品质控制建议

  • 来料检验:抽样检测频率、输出波形、工作状态在不同温度与供电条件下的稳定性。
  • 可靠性测试:包括高低温循环、湿热试验与振动测试,保证器件在目标应用场景下的长期可靠性。
  • ESD 与静电防护:在搬运与贴片过程中应采取静电防护措施,避免静电放电对内部振荡电路造成损伤。

七、常见问题与解决思路

  • 输出不稳定或抖动:检查电源去耦、接地布局与 PCB 上的噪声源;确认负载电容与输入阻抗匹配。
  • 工作频率偏差超标:确认供电电压、温度条件与出厂标称是否一致,必要时进行系统级校准。
  • 焊接后失效:核查回流曲线是否符合器件耐温规范,排查焊接参数与助焊剂残留问题。

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
