CJO05-250003320B30 — 25MHz 3.3V 贴片有源晶振产品概述

一、产品简介

CJO05-250003320B30 是长晶(CJ)出品的一款高稳定性贴片有源晶振,工作频率为 25.000 MHz,输出模式为 CMOS,工作电压 3.3V。该器件采用 SMD3225-4P 小型贴片封装,适合自动贴装和回流焊工艺,面向嵌入式系统、通信设备和各类数字时钟源应用场景。

二、主要参数

  • 频率:25 MHz(标称)
  • 输出模式:CMOS(推挽输出,典型全摆幅)
  • 工作电压:3.3 V
  • 工作电流:典型 10 mA
  • 频率稳定度:±20 ppm(含初始容差、温度影响及老化等)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装:SMD3225-4P(3.2 × 2.5 mm)
  • 型号:CJO05-250003320B30
  • 品牌:CJ(江苏长电/长晶)

三、产品特点

  • 高频率稳定、相位噪声低,适合作为系统主时钟源或采样时钟。
  • CMOS 输出兼容主流 3.3 V 逻辑接口,输出摆幅大、上升/下降时间短,便于驱动 FPGA、MCU 或其他数字电路。
  • 小封装、低外形高度,利于空间受限的产品设计与高密度布板。
  • 宽温工作范围(-40~+85 ℃)满足工业级环境需求。
  • 良好的一致性和可回流焊可靠性,适配自动化生产线。

四、典型应用

  • 嵌入式微控制器/微处理器系统时钟。
  • FPGA/CPLD 时钟源与系统同步。
  • 通信设备、网络芯片参考时钟(如 PHY/收发器)。
  • 数模/模数转换器采样时钟、测量和测试设备。
  • 消费电子、工业控制与物联网终端等需要稳定时钟的场合。

五、封装与安装建议

  • 使用标准 SMD3225-4P 封装 PCB 焊盘尺寸;遵循厂商推荐的 PCB 封装与过孔布局,避免器件下方过多通孔。
  • 电源引脚附近建议并联去耦:常用 0.1 μF 与 0.01 μF 陶瓷电容靠近 Vdd 引脚布置,以抑制电源噪声并提升瞬态响应。
  • 输出线尽量短且走直线,避免与高速差分线或大电流回路并行,以降低串扰与辐射。
  • 保持器件周边 2–3 mm 的金属平面清洁区,减少寄生电容和干扰耦合。
  • 回流焊时遵循厂家或行业 Pb-free 回流曲线,避免长时间过高温度。

六、使用与注意事项

  • CMOS 输出为推挽结构,负载能力有限,若需驱动多个下游负载或长距传输建议加缓冲驱动器或使用合适的上拉/终端策略。
  • 频率稳定度受供电品质、温度与振荡器老化影响,系统设计时应留有裕量。
  • 在高 EMI 环境中,必要时增加滤波与屏蔽措施。
  • 贮存与搬运注意防潮、防静电,遵循晶振类元件的常规包装与存储规范。

七、采购与质保信息

  • 型号:CJO05-250003320B30,封装 SMD3225-4P,品牌 CJ(长晶/长电)。
  • 订购前确认批次频率偏差、长期老化要求与是否需要特殊测试(如高温老化、相位噪声测试等)。
  • 建议向有资质的分销商或厂家直接采购以确保原装与出货一致性,并咨询具体的 RoHS、REACH 等合规证书及保修条款。

如需样片参数曲线、封装尺寸图和推荐 PCB 封装文件(Gerber/座标),可进一步提供以便工程设计验证与布局优化。

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
