SX3M8.192B10F20TNN有源晶振产品概述

一、产品定位与核心优势

SX3M8.192B10F20TNN是星通时频(SCTF) 推出的工业级CMOS输出有源晶振,专为需要精准时钟同步、宽温环境适应性的电子设备设计。核心优势集中在:

  1. 小封装(SMD3225-4P)适配高密度PCB布局;
  2. 宽温范围(-40℃~+85℃)覆盖工业/车载恶劣环境;
  3. 稳定的频率特性(±20ppm全温稳定度)满足多数数字系统时序要求;
  4. 3.3V单电源+10mA低功耗,平衡性能与功耗成本。

二、关键性能参数详解

1. 频率精度与稳定度

  • 常温频差±10ppm:以8.192MHz基准计算,频率偏差约±81.92Hz,满足MCU、FPGA等数字芯片的时钟输入精度要求(多数工业级系统要求≤±50~100ppm);
  • 全温频率稳定度±20ppm:覆盖-40℃~+85℃工作温区,同时兼容电源波动、负载变化等外部干扰,确保时钟信号长期稳定(无跳频、漂移)。

2. 输出与电源特性

  • CMOS输出:逻辑电平与3.3V系统完全兼容,无需额外电平转换电路,可直接驱动多数数字IC的时钟输入端;
  • 电源与功耗:3.3V单电源供电,典型工作电流10mA,在保证输出驱动能力的前提下,避免功耗过高影响电池续航(适合物联网网关、便携设备)。

3. 环境适应性

  • 工作温区:-40℃~+85℃(工业级标准),可适应户外传感器、车载电子的极端温度场景;
  • 存储温区:-55℃~+125℃,满足长期库存或运输过程中的环境变化。

三、封装与可靠性设计

1. 小型化封装

采用SMD3225-4P封装(尺寸3.2mm×2.5mm×0.8mm),是当前主流小型化有源晶振封装之一,适合智能终端、微型传感器等空间紧凑的设备,可有效节省PCB面积。

2. 可靠性保障

  • 焊接可靠性:符合IPC-A-610标准,回流焊温度曲线兼容常规SMT工艺(峰值温度≤245℃);
  • 抗干扰设计:内置滤波电路,减少电磁干扰(EMI)对时钟信号的影响,同时具备静电防护(ESD)能力(符合IEC 61000-4-2标准);
  • 老化特性:年老化率≤±5ppm/年,长期使用后频率漂移仍在可接受范围内,无需频繁校准。

四、典型应用场景

该产品的性能特性匹配多领域需求,核心应用包括:

  1. 工业控制设备:PLC(可编程逻辑控制器)、伺服驱动器、工业传感器节点——宽温适应车间/户外环境,精准时钟保证控制时序同步;
  2. 通信终端:4G/5G小基站、无线AP、物联网网关——CMOS输出兼容射频芯片,稳定度满足通信信号同步要求;
  3. 车载电子:车载导航、ADAS辅助系统、车载通信模块——-40℃~+85℃温区适配车载低温启动、高温暴晒场景;
  4. 消费电子:智能手表、智能家居中控、便携医疗设备——小封装+低功耗适合小型化、电池供电设计。

五、选型与使用注意事项

  1. 选型匹配:确认系统时钟频率需求(8.192MHz常见于串口、SPI、I2C总线的基准时钟),电源电压需稳定在3.3V±5%范围内;
  2. 焊接规范:避免手工焊接,建议采用回流焊工艺,焊接后需检查引脚无虚焊、短路;
  3. PCB布局建议:晶振尽量靠近时钟输入端(距离≤5cm),走线避免靠近高频信号线,必要时增加接地屏蔽;
  4. 保存要求:未焊接产品存储于常温干燥环境(25℃±5℃,湿度≤60%RH),避免静电损伤(需使用防静电包装)。

总结

SX3M8.192B10F20TNN有源晶振凭借精准频率、宽温可靠性、小型化设计,成为工业、通信、车载等领域的高性价比时钟解决方案,可满足多数数字系统对时钟信号的核心需求。

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
