SX7M20.000M20F30TNN有源晶振产品概述

一、产品基本信息

SX7M20.000M20F30TNN是星通时频(SCTF)推出的一款工业级有源CMOS晶振,采用SMD7050-4P贴片封装(标准尺寸7.0mm×5.0mm×1.5mm),4引脚设计支持自动化贴装,适配多数电子设备的小型化、高密度PCB布线需求。该型号针对20MHz核心频率优化,兼顾精度、可靠性与环境适应性,是数字电路、通信系统的通用基准时钟源。

二、核心频率性能

  1. 标称频率:20MHz
    为数字电路、通信芯片的常用基准频率,可直接作为MCU、FPGA、射频收发器的时钟输入,无需额外分频/倍频处理,简化系统设计。

  2. 常温频差:±20ppm(百万分之二十)
    换算为频率偏差为**±400Hz**(20MHz×20×10⁻⁶),在25℃常温环境下,频率稳定性满足90%以上常规应用的精度要求(如数据传输、时序控制)。

  3. 频率稳定度:±30ppm
    该参数涵盖工作温度范围(-40℃~+85℃)内的总频率变化,相比常温频差,进一步保证高低温环境下的时钟精度,避免因温度波动导致系统时序紊乱、数据丢包。

三、电气特性参数

  1. 工作电压范围:1.62V~3.63V
    覆盖1.8V、3.3V等主流数字电路电压,兼容低功耗嵌入式系统(如可穿戴设备)与常规电源设计,无需额外电压转换电路,降低系统开发成本。

  2. 工作电流:典型值10mA
    在有源晶振中属于常规功耗水平,不会对系统整体功耗造成显著负担,适合对功耗敏感的小型设备(如智能家居终端)。

  3. 输出模式:CMOS逻辑电平
    高电平接近电源电压,低电平接近0V,可直接匹配TTL/CMOS逻辑门电路,无需电平转换芯片,提升系统集成度。

四、环境适应性

SX7M20.000M20F30TNN的工作温度范围为-40℃~+85℃,属于工业级温度规格,能够适应以下场景:

  • 户外设备(气象监测、安防摄像头)的高低温波动;
  • 工业控制现场(PLC、传感器节点)的严苛环境;
  • 部分车载电子系统(仪表盘、胎压监测模块)的温度要求。

五、典型应用场景

结合参数特性,该晶振适用于:

  1. 工业控制:PLC可编程逻辑控制器、伺服电机控制系统、工业传感器模块(依赖稳定时钟保证数据采集时序);
  2. 通信设备:小型基站、WiFi/蓝牙模块、射频收发器(20MHz为通信芯片常用基准频率);
  3. 消费电子:智能家居网关、智能手表、智能音箱(宽电压+小封装适配小型化设计);
  4. 车载电子:车载信息娱乐系统、TPMS胎压监测模块(工业级温度满足车载环境)。

六、产品核心优势

  1. 宽电压兼容:1.62V~3.63V覆盖主流电压平台,无需定制电源方案;
  2. 工业级可靠性:-40℃~+85℃温度范围+±30ppm稳定度,保证严苛环境下的时钟精度;
  3. 高集成度输出:CMOS输出直接匹配数字电路,简化系统架构;
  4. 小型化封装:SMD7050-4P体积小,适配高密度PCB设计;
  5. 品牌保障:SCTF星通时频专注时频器件研发,产品经过振动、冲击、老化等严格测试,质量稳定可靠。

该型号通过优化频率精度与环境适应性,可满足多数中高端电子设备的时钟需求,是工业、通信、消费电子领域的高性价比选择。

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
