OT322522.1184MJBA4SL 产品概述
一、产品简介
OT322522.1184MJBA4SL 是一款小型贴片有源晶振，工作频率 22.1184MHz，适用于对频率精度和温度范围有一定要求的嵌入式系统与通信终端。器件采用 SMD3225-4P 封装，输出为 CMOS 电平，供电电压兼容 1.8V 至 3.3V，多温度等级和稳定性参数适配工业与民用场景。该系列由 YXC（扬兴科技）生产，性能可靠，便于高速自动贴装与批量应用。
二、主要参数
- 频率：22.1184 MHz
- 常温频差（出厂初始容差）：±10 ppm
- 频率稳定度（环境温度-40℃~+85℃）：±20 ppm
- 输出模式：CMOS（推挽输出，兼容常见数字输入）
- 工作电压：1.8 V ~ 3.3 V
- 工作温度：-40℃ ~ +85℃
- 封装：SMD3225-4P（4焊盘贴片）
- 品牌：YXC 扬兴科技
三、产品特性与优势
- 高频率精度高：22.1184MHz 常用于串口波特率分频、音视频与通信同步等场景，配合 ±10ppm 初始容差可实现高精度时钟源。
- 宽电压兼容：1.8V~3.3V 设计，适配低功耗与标准 3.3V 系统。
- 工业级温度范围：-40℃~+85℃，适用工业控制、车载子系统及恶劣环境。
- 小封装、易贴装：SMD3225-4P 小尺寸便于自动化 SMT 工艺与高密度 PCB 布局。
- CMOS 输出：直接驱动 MCU / FPGA 等数字输入，无需外部放大器。
四、典型应用
- MCU、SoC 的主时钟或外部参考时钟
- 串口通信与调制解调器（例如 UART 波特率分频参考）
- 工业控制与自动化设备时钟源
- 网络设备、消费电子和仪表的稳定频率参考
五、封装与布局建议
- 引脚功能一般包含 VCC、GND、OUT、NC（视具体封装管脚定义）。请参阅器件数据手册确认引脚排列。
- 电源去耦：VCC 旁放置 0.01µF ~ 0.1µF 陶瓷电容，靠近器件电源脚焊盘，以减少电源噪声。
- 布局：输出走线尽量短且直，避免与高频开关电源或大电流回路并行，地线采用连续的参考地平面以降低回流干扰。
- 若系统对上电时序敏感，注意晶振的启动时间与系统复位策略协调。
六、选型与注意事项
- 确认系统接受的输出电平与上拉/下拉需求，CMOS 输出通常直接驱动数字输入，但若需长线驱动或多点分发，考虑加缓冲或终端匹配。
- 对频率精度有更高需求的应用，应参照具体温漂曲线与老化特性并预留余量。
- 采购与替换时，保持封装（SMD3225-4P）与电气参数一致，避免因引脚排列差异导致焊接或功能异常。

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.
