SX2M50.000M20F30TNN有源晶振产品概述

SX2M50.000M20F30TNN是星通时频(SCTF) 推出的一款工业级CMOS输出有源晶振,针对50MHz频率需求场景设计,兼顾宽电压适配、宽温稳定与小型化封装,可满足工业控制、通信、车载等多领域的时钟同步需求。

一、产品定位与核心设计逻辑

该产品属于工业级有源晶振范畴,采用高精度石英晶体谐振器+CMOS振荡电路架构,无需外部匹配元件即可直接输出稳定时钟信号。设计上重点平衡了「精度、环境适应性、体积与成本」,适合对时钟漂移要求不极端但需稳定工作的场景,避免了温补/恒温晶振的成本冗余。

二、关键技术参数详解

1. 频率精度与稳定度

  • 基准频率:50MHz,是工业控制、通信模块的常用中频/时钟频率,适配多数MCU、FPGA的时钟输入范围;
  • 常温频差:±20ppm(25℃环境下),换算为绝对偏差仅1kHz(50MHz×20×10⁻⁶),可满足8位/16位数字电路的同步精度要求;
  • 全温频率稳定度:±30ppm(-40℃~+85℃范围内),覆盖工业级温度波动,避免极端环境下时钟漂移导致的系统误差(如PLC逻辑运算错误、传感器数据丢包)。

2. 电气性能

  • 输出模式:CMOS,输出电平与主流3.3V/1.8V数字电路兼容,无需电平转换即可对接MCU、DSP、通信芯片的时钟引脚;
  • 工作电压:1.62V~3.63V,覆盖低功耗物联网模块的1.8V供电、普通3.3V系统,适配范围广(如蓝牙5.0模块、智能手环);
  • 工作电流:典型值20mA,在有源晶振中属于常规水平,满足多数系统的功耗预算(单节锂电池供电设备可兼容)。

3. 机械与环境参数

  • 封装:SMD2520-4P,即2.5mm×2.0mm的贴片封装,4引脚布局,适合小型化PCB设计(如传感器节点、车载OBD模块);
  • 工作温度:-40℃~+85℃,工业级温度范围,可适应户外设备、汽车舱内/外的温度变化;
  • 存储温度:-55℃~+125℃(行业常规补充),满足长期存储的可靠性要求。

三、典型应用场景

SX2M50.000M20F30TNN的参数特性使其适配以下核心场景:

  1. 工业控制:PLC(可编程逻辑控制器)、电机驱动板、温度传感器模块,宽温稳定可应对车间高低温环境;
  2. 通信与物联网:蓝牙5.0网关、LoRa终端、WiFi热点,宽电压适配不同模块的供电设计,50MHz频率支持中频信号处理;
  3. 车载电子:仪表盘时钟、ADAS辅助驾驶传感器(如毫米波雷达),工业级温度耐受汽车启动/行驶中的温度波动;
  4. 消费电子:智能手环、智能音箱的内部时钟,小封装节省空间,低电压适配低功耗芯片。

四、品牌与可靠性说明

星通时频(SCTF)是国内专注于时频器件研发生产的厂商,SX2M50.000M20F30TNN经过多项可靠性验证:

  • 老化测试:168小时高温老化,确保频率漂移≤规格值;
  • 温循测试:-40℃~+85℃循环10次,验证全温范围的稳定度;
  • 焊接兼容性:支持SMT回流焊(温度曲线符合IPC标准),适合量产自动贴装;
  • 跌落测试:满足2m高度跌落(包装状态),降低运输损耗。

该产品供货稳定,可提供样品测试与批量定制服务,适合研发阶段验证与量产阶段的稳定供应。

五、产品优势总结

  1. 宽电压适配:1.62V~3.63V覆盖主流数字系统供电;
  2. 工业级稳定:-40℃~+85℃全温稳定度±30ppm;
  3. 小体积设计:2.5×2.0mm封装节省PCB空间;
  4. 即插即用:CMOS输出无需电平转换,简化电路设计。

SX2M50.000M20F30TNN是一款性价比突出的工业级有源晶振,可有效解决多场景下的时钟同步需求。

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
