  • 嵌入式系统与消费电子:需要低抖动、兼容 3.3V 或 2.5V 电平的微控制器时钟源
  • 汽车电子(符合温度范围下的非严苛车规应用)

四、电气与环境规格(概要)

  • 频率(标称):7.680 MHz
  • 输出形式:HCMOS(CMOS 逻辑电平,推挽输出)
  • 供电电压:2.5 V ~ 3.3 V
  • 静态/工作电流:典型 10 mA(根据负载与工作条件略有变化)
  • 常温频差:±10 ppm(25 ℃)
  • 温度范围内频率稳定度:±20 ppm(-40 ℃ ~ +85 ℃)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SMD3225-4P(3225 4 引脚)

(注:以上为典型与出厂标注指标;在具体设计中应参考厂商完整版数据手册以获取绝对极限、时序图、上电/复位要求与详细电气测量条件。)

五、封装与 PCB 布局建议

  • 封装形式为 SMD 3225(3.2 × 2.5 mm),4 引脚布局,适合自动贴片与回流焊工艺。
  • 推荐在晶振 VCC 引脚附近放置 0.1 µF 陶瓷去耦电容,尽量靠近器件引脚焊盘焊接以抑制电源噪声。
  • 输出侧负载与追随电路(如缓冲器或 MCU 时钟输入)应按器件电气规格合理匹配,避免过大负载导致输出欠佳。
  • 回流焊规范建议遵循厂商回流曲线与焊接温度限制,避免超过器件承受温度以保持长期可靠性。
  • 在高速或敏感电路附近布线时,注意减少输出线的走线长度,必要时增加地平面与屏蔽以降低干扰与串扰。

六、型号升级与兼容说明

本产品型号在内部管理或系列升级中标注为 1532H4-7.680J33DTSTL,厂商同时给出的升级型号/替代型号为 1532H-7.680J33DTSTL。两者在电气与机械接口方面保持高度兼容,但在批次与包装编码上可能有所区分。建议在采用前向供应商确认具体批次的出厂测试报告与机械图纸,确保与现有设计完全匹配。

总结:1532H4-7.680J33DTSTL 提供了小尺寸封装下的高精度时钟解决方案,适合需要工业温度范围与稳定频率的各类电子系统。为确保最佳性能,请在设计时参考完整数据手册并按推荐的 PCB 布局及电源去耦方案进行实现。

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
