X322524576MOB4SI 产品概述
一、产品简介
X322524576MOB4SI 为扬兴科技（YXC）出品的无源贴片晶振，封装尺寸为 SMD3225-4P（3.2 × 2.5 mm）。标称频率 24.576 MHz，常温初始频差 ±10 ppm，工作温度范围 -40℃ ～ +85℃，频率稳定度（温度影响）可达 ±20 ppm，推荐负载电容 12 pF。该器件为无源器件，适配常见的 Pierce 晶体振荡电路，常用于对频率精度和稳定性要求较高的系统。
二、性能要点
- 频率：24.576 MHz（常用于 48 kHz 家族音频时钟等应用）
- 初始频差（常温）：±10 ppm
- 温度稳定度：±20 ppm（-40℃～+85℃）
- 负载电容：12 pF（指定值，电路设计时应按此匹配）
- 封装：SMD3225-4P（小型贴片，适合高密度 PCB 布局）
- 类型：无源晶体（需外部晶振电路驱动）
三、典型应用场景
- 数字音频系统（I2S、DAC/ADC 时钟，48 kHz/96 kHz 系列采样率）
- 通信设备与接口电路的参考时钟
- 微控制器与 SoC 的高精度外部时钟源
- 工业与消费类电子需稳定时钟的场合
四、设计与使用建议
- 负载电容匹配：负载电容 CL = 12 pF。若使用对称电容 C1 = C2，则近似关系 CL ≈ (C1·C2)/(C1+C2) + Cstray；取 Cstray（线路与封装寄生）约 2–5 pF，则 C1 ≈ C2 ≈ 2·CL - Cstray，推荐取值约 18–22 pF（常用 22 pF）。
- 驱动与电路拓扑：作为无源晶体，需与振荡器管脚匹配（例如 MCU/PLL 内部放大器或专用晶振驱动器）。避免过大驱动功率以免引起频率漂移或损伤晶体。
- 布局注意：晶振引脚附近避免大面积地或噪声信号线，尽量缩短连接线，参照厂商推荐焊盘尺寸与回流曲线。
- 回流焊接：遵循晶振制造商的温度曲线与工艺要求，避免过热或长时间高温。
五、可靠性与检验
X322524576MOB4SI 设计适应工业温区（-40℃～+85℃），在正常使用条件下应满足长期老化与环境应力要求。建议在样机阶段进行系统级时钟漂移、相位噪声与启动时间测试，并在批量采购前与供应商确认老化、ESD 与可靠性测试数据。
六、选型与采购建议
选择时确认晶振的温漂、初始频差与目标应用的容差匹配；若需更严格温漂或特定认证（如汽车级或军工级），请向厂商索取对应型号或定制方案。下单时备注完整型号 X322524576MOB4SI、封装 SMD3225-4P 与要求的频差/稳定度参数，以确保交付的器件满足设计需求。

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.
