SX3DF125.000B20F30DNN有源晶振产品概述

一、核心技术指标

SX3DF125.000B20F30DNN是SCTF(星通时频) 推出的工业级有源晶振,核心参数精准匹配中高速数字系统的时钟需求:

  • 输出频率:125MHz(基频设计,信号纯度高,无倍频失真);
  • 频率精度:常温下±20ppm(对应125MHz时偏差≤2.5kHz,满足多数高速场景的时钟误差要求);
  • 全温稳定度:±20ppm(覆盖-40℃~+85℃工作温度,宽温环境下频率偏移可控);
  • 输出模式:LVDS(低电压差分信号,抗干扰能力强);
  • 供电参数:3.3V单电源,工作电流40mA(低功耗设计,减少系统电源负担);
  • 封装尺寸:SMD3225-6P(3.2×2.5mm贴片封装,6引脚,小型化集成友好)。

二、电气性能与输出特性

1. LVDS输出优势

LVDS(低电压差分信号)采用1.2V差分摆幅,相比单端CMOS输出,具备三大核心优势:

  • 抗干扰强:差分传输可抵消共模噪声,适合工业现场、通信基站等电磁环境复杂的场景;
  • 高速传输:支持125MHz高频信号低损耗传输,匹配10G以太网、高速串口等协议;
  • 信号完整性:上升/下降时间快(典型<1ns),减少信号反射与串扰问题。

2. 供电与功耗平衡

3.3V单电源兼容主流数字电路(如PLC、路由器、服务器),无需额外电平转换;40mA工作电流处于同规格产品的优势区间——既保证时钟信号的稳定振荡,又降低了嵌入式系统、便携设备的功耗压力。

3. 宽温频率稳定性

±20ppm的全温稳定度,意味着在-40℃(低温启动)至+85℃(高温负载)范围内,时钟频率偏差始终≤2.5kHz,可避免因温度变化导致的系统时钟偏移,确保数据传输、控制指令的准确性。

三、封装与机械特性

该晶振采用SMD3225-6P贴片封装,尺寸仅3.2mm×2.5mm×1.0mm(典型厚度),属于微型化设计,可有效节省PCB布局空间,适配高密度集成设备(如小型工业控制器、微型通信模块)。

6引脚专为LVDS输出优化,引脚定义清晰(包含电源正、地、差分输出对、使能端),支持自动化贴装工艺,焊接兼容性好,适合批量生产场景。

四、环境适应性与可靠性

SX3DF125.000B20F30DNN具备工业级可靠性:

  • 温度范围:-40℃~+85℃,可满足户外设备、车间、变电站等极端温度场景;
  • 湿度耐受:符合5%~95%非凝结环境要求,适应高湿度地区;
  • 长期稳定性:内置高精度石英谐振器,长期老化率≤±5ppm/年(行业优良水平),减少设备维护成本。

五、典型应用场景

凭借高频、稳定、抗干扰特性,该晶振广泛覆盖以下领域:

  1. 工业控制:PLC、变频器、伺服驱动器的时钟源,保障自动化系统精准控制;
  2. 通信设备:基站、路由器、光传输设备的参考时钟,支持10G/40G以太网传输;
  3. 消费电子:高清机顶盒、游戏主机的音视频同步时钟,提升画面/声音一致性;
  4. 医疗仪器:监护仪、超声设备的采样时钟,确保数据采集准确性;
  5. 车载扩展:若通过汽车级认证,可用于车载通信、信息娱乐系统的时钟参考。

六、品牌与质量保障

SCTF(星通时频)是国内专注时频器件的专业厂商,产品通过ISO9001、RoHS、REACH认证,生产流程全自动化,每批次晶振经参数测试+老化筛选,确保一致性与可靠性,为客户提供稳定供货。

该产品以“高频稳定+低功耗+工业级适应性”为核心,精准匹配中高速数字系统的时钟需求,是工业控制、通信等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
