SX3M3.6864M20F30TNN 有源晶振产品概述

一、产品基本信息

SX3M3.6864M20F30TNN是星通时频(SCTF) 推出的工业级SMD封装有源晶振,采用SMD3225-4P 4脚贴片封装(尺寸3.2mm×2.5mm),专为数字电路时钟基准设计,兼顾小型化、宽温可靠性与电气兼容性,可直接替代无源晶振提升系统时钟稳定性。

二、核心电气参数详解

该型号参数针对主流数字系统需求优化,关键性能如下:

1. 频率特性

  • 标称频率:3.6864MHz,是串口通信(如115200bps波特率)、微控制器时钟的典型基准频率(3.6864M = 115200bps × 32),适配UART、SPI等接口的时钟需求;
  • 常温频差:±20ppm(百万分之一),即频率偏差约±73.7μHz,满足普通数字电路的时钟精度要求,避免数据传输误码;
  • 频率稳定度:±30ppm(总稳定度),包含温度、电压波动等因素,保证-40℃~+85℃范围内频率偏差不超过±110.6μHz,可靠性符合工业级标准。

2. 输出与电源特性

  • 输出模式:CMOS电平输出,与TTL/CMOS逻辑电路完全兼容,可直接连接MCU、FPGA、通信芯片等,无需额外电平转换电路,简化硬件设计;
  • 工作电压:1.62V~3.63V,覆盖1.8V、3.3V等主流数字电路工作电压,适配低功耗嵌入式系统、工业控制模块等不同电源架构;
  • 工作电流:10mA(典型值),在有源晶振中属于常规功耗水平,稳定工作的同时不会显著增加系统总功耗。

三、工作环境与可靠性

该型号支持工业级宽温范围:-40℃+85℃,可适应户外、车载、工业现场等温度变化剧烈的场景,避免因温度波动导致频率漂移,保证系统稳定运行(对比商业级070℃,可靠性提升30%以上)。

四、典型应用场景

SX3M3.6864M20F30TNN的性能特点使其适配多种数字系统,典型应用包括:

  1. 串口通信模块:RS232、RS485接口的时钟基准,保证115200bps及以下波特率的稳定传输,常用于工业传感器、PLC通信;
  2. 微控制器(MCU)时钟源:STM32、AVR、PIC等MCU的外部晶振,宽电压兼容MCU IO电压,替代无源晶振提升时钟稳定性;
  3. 消费电子小型化设计:智能穿戴(如智能手环、手表)、小型家电(如智能插座)的控制电路时钟,SMD3225封装节省PCB空间;
  4. 工业控制设备:PLC、变频器、传感器节点的时钟基准,宽温特性适应工业现场-20℃~+60℃的常规环境,极端温度下仍可靠工作;
  5. 通信接口电路:蓝牙模块、Wi-Fi模块的辅助时钟,辅助射频电路实现稳定的数据收发。

五、产品核心优势

  1. 宽电压与宽温双重兼容:1.62V~3.63V电压范围+工业级宽温,适配不同电源与环境需求;
  2. 小封装高集成:SMD3225-4P封装(3.2×2.5mm),比常规DIP封装节省70%以上PCB空间,适合小型化产品;
  3. 直接逻辑兼容:CMOS输出无需电平转换,降低硬件设计复杂度与成本;
  4. 精准稳定的频率特性:常温频差±20ppm+总稳定度±30ppm,满足大多数数字系统的时钟精度要求。

该产品凭借高可靠性、宽适配性与小型化设计,成为工业控制、消费电子、通信等领域的优选时钟基准器件。

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
