8875H-20.000NV33DTL 产品概述
一、产品简介
8875H-20.000NV33DTL 是杭州晶体（HCI/杭晶）出品的一款高精度温度补偿晶体振荡器（TCXO）。器件输出为标准 CMOS 电平，标称频率 20.000 MHz，工作电压 3.3 V，工作温度范围 -40 ℃ 至 +85 ℃。该器件以“高精度、高稳定性”为设计目标，适合对频率精度与温度稳定性有严格要求的系统使用。
二、主要性能指标
- 标称频率：20.000 MHz
- 输出模式：CMOS 方波输出
- 工作电压：3.3 V
- 初始频率精度（初始误差）：±1 ppm
- 频率稳定度 / 温度补偿后：±0.28 ppm（±280 ppb）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装形式：SMD 7050-4P（尺寸 7.0 × 5.0 mm，4 引脚）
这些参数在典型测试条件下获得，具体性能以出厂检验报告为准。
三、主要应用场景
- 通信基站与网络设备中的时钟源与参考频率
- 精密测量仪器、测试设备的基准时钟
- 高可靠性嵌入式系统、定位与导航系统（需高稳定度参考）
- 无线电、光纤传输、频率合成与参考模块等领域
四、封装与 PCB 布局建议
- 建议在 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；同时在电源线上考虑加入适当的滤波与阻抗控制。
- 输出线尽量短且恒阻抗，避免长距离走线产生振铃或串扰。
- 器件底部请保证良好接地，散热通道与地平面连通可提高稳定性。
- 采用推荐的 7050 封装焊盘和回流温度曲线，遵守元件湿热等级与回流规范以避免焊接损伤。
五、选型与使用注意
- 初始精度 ±1 ppm 与温度补偿后 ±0.28 ppm 表明该 TCXO 适用于对长期及温度变化敏感的系统；在选型时应核对目标应用的相位噪声、抖动等额外指标（如有要求），并参考厂方完整规格书。
- 建议在最终系统中进行实际环境下的温漂验证与老化测试，确保满足长期可靠性要求。
- 注意静电防护与储运湿敏等级，元件应在规定条件下保存与回流焊接。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
