SX3M50.000M20F30TNN有源晶振产品概述

一、产品基本定位与品牌背景

SX3M50.000M20F30TNN是星通时频(SCTF) 推出的一款高频CMOS输出有源晶振,针对需要稳定50MHz时钟基准、宽电压适配的电子设备设计。作为有源晶振,其内置振荡电路,无需外部匹配电容/电感即可直接输出稳定时钟信号,相比无源晶振简化了电路设计,适合小型化、高集成度的应用场景。SCTF作为国内专业的时频器件供应商,其产品覆盖工业级、消费级等多个领域,该型号延续了品牌在时钟稳定性与可靠性方面的技术优势。

二、核心性能参数详解

该型号的核心参数围绕时钟精度、电气兼容性、功耗三大维度设计,具体如下:

  1. 频率特性:标称频率为50MHz,是嵌入式系统、通信模块中常见的时钟基准(可通过分频适配UART、SPI、I2C等外设的不同频率需求);常温(25℃)频差控制在±20ppm内,即实际输出频率与50MHz的偏差不超过1kHz(50×10⁶ × 20×10⁻⁶ = 1000Hz),满足大多数数字电路的精度要求;全温范围内频率稳定度为±30ppm,可覆盖温度变化带来的频率漂移,保证宽温下的时钟一致性。
  2. 输出特性:采用CMOS输出,输出电平兼容3.3V/2.5V/1.8V等主流数字接口,无需电平转换即可直接连接MCU、FPGA、无线收发器等芯片,降低系统设计复杂度。
  3. 电气特性:工作电压范围为1.62V~3.63V,覆盖了锂电池(3.7V放电后)、单片机(3.3V/2.5V)、低功耗SoC(1.8V)等常见电源场景;工作电流为20mA,在有源晶振中属于中等功耗,兼顾稳定性与功耗平衡。

三、封装与接口特性

该型号采用SMD3225-4P封装,尺寸为3.2mm×2.5mm×0.8mm(典型厚度),属于小型化贴片封装,可有效节省PCB空间,适配便携设备、小型模块的高密度布局需求。4引脚设计(通常包含VCC、GND、CLK_OUT、NC/备用脚),接口简单易焊接,支持回流焊、波峰焊等主流贴片工艺,适合自动化生产。

四、工作环境与可靠性

  1. 温度范围:工作温度覆盖-40℃~+85℃,属于工业级温度范围,可适应户外、车载、工业现场等严苛环境(如低温下的户外传感器、高温下的工业PLC),无需额外温度补偿电路即可保持时钟稳定。
  2. 可靠性:SCTF对该型号进行了振动、冲击、湿度等可靠性测试,符合GB/T 14022.1等电子元器件标准,可长期稳定工作(典型MTBF超过10万小时),适用于对可靠性要求较高的工业与通信设备。

五、典型应用场景

该型号的宽电压、宽温、小封装特性,使其适用于以下场景:

  1. 嵌入式系统:单片机(如STM32、ATmega系列)、ARM开发板的主时钟基准,提供稳定的50MHz时钟,支持外设与CPU的同步运行;
  2. 无线通信模块:蓝牙、WiFi、LoRa等模块的中频时钟或参考时钟,50MHz是常见的收发器中频频率,保证信号传输的准确性;
  3. 工业控制设备:PLC、传感器节点、工业网关的时钟源,宽温特性适配车间、户外等环境;
  4. 消费电子:智能穿戴(手表、手环)、便携音箱、无人机飞控的辅助时钟,宽电压适配锂电池的充放电状态变化。

六、选型与使用注意事项

  1. 电压匹配:确认系统电源电压在1.62V~3.63V范围内,避免过压(>3.63V)损坏器件,或欠压(<1.62V)导致输出不稳定;
  2. 布线规范:时钟输出线应尽量短,远离高频干扰源(如电源、射频电路),避免串扰影响时钟精度;
  3. 焊接工艺:回流焊温度曲线需符合SMD3225封装的标准(峰值温度≤260℃,时间≤10s),避免热冲击导致器件失效;
  4. 负载考虑:CMOS输出的负载能力约为10pF~20pF,需确认连接的芯片输入电容不超过该范围,若负载过重可考虑增加缓冲器。

该型号凭借稳定的时钟性能、宽适配性与小封装优势,成为众多电子设备时钟设计的实用选择,可满足工业、消费、通信等多领域的需求。

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.
