SX5M4.9152M20F30TNN有源晶振产品概述

一、产品基本定位与核心属性

SX5M4.9152M20F30TNN是星通时频(SCTF) 推出的一款工业级CMOS有源晶振,核心定位为中高精度、宽电压适配、工业温度范围的时钟基准器件。产品采用SMD5032-4P贴片封装,体积紧凑(5.0mm×3.2mm×1.2mm),输出模式为CMOS,可直接驱动MCU、FPGA等数字电路的时钟输入引脚,无需额外缓冲电路,适用于对频率稳定性要求较高的嵌入式系统、工业控制及通信接口设备。

二、关键性能参数详解

该晶振的核心参数直接决定了其适用场景,具体拆解如下:

1. 频率与精度指标

  • 标称频率:4.9152MHz(串口通信领域标准基准频率,是19.2MHz的1/4,可直接校准9600bps、19200bps等波特率,避免数据传输丢包);
  • 常温频差:±20ppm(常温25℃下,频率偏差不超标称值的百万分之20,即实际频率范围为4.9152MHz±0.098304Hz,满足大多数数字电路的时钟精度需求);
  • 频率稳定度:±30ppm(包含温度变化、电压波动等外部因素的总稳定度,即-40℃~+85℃范围内,频率最大偏差不超±30ppm,是工业级应用的核心可靠性指标)。

2. 电气特性

  • 工作电压:1.62V~3.63V(覆盖1.8V、3.3V等主流嵌入式系统电压,兼容低功耗MCU与高电压工业设备);
  • 工作电流:10mA(典型值,在保证频率稳定性的前提下,兼顾功耗与输出驱动能力,适合对功耗敏感但需稳定时钟的场景);
  • 输出模式:CMOS(输出电平与TTL/CMOS逻辑兼容,高电平≥0.8×VCC,低电平≤0.2×VCC,可直接匹配数字电路输入)。

3. 环境适应性

  • 工作温度:-40℃~+85℃(工业级温度范围,可适应户外设备、车间环境等极端温度场景);
  • 存储温度:-55℃~+125℃(常规工业级存储要求,保证运输与存储过程中的器件可靠性)。

三、封装与引脚配置

产品采用SMD5032-4P 贴片封装,引脚定义需注意焊接极性:

  • 引脚1:VCC(电源输入,需匹配1.62V~3.63V电压);
  • 引脚2:GND(接地,需可靠连接系统地);
  • 引脚3:NC(空脚,无需焊接);
  • 引脚4:OUT(CMOS时钟输出,直接连接MCU/MPU的外部时钟输入引脚)。

封装尺寸符合主流PCB设计的空间要求,可通过回流焊、波峰焊等工艺焊接,焊接温度需遵循SCTF规范(如回流焊峰值温度≤260℃,时间≤10秒)。

四、典型应用场景

SX5M4.9152M20F30TNN的性能特点使其适用于以下场景:

  1. 串口通信系统:RS232/RS485接口模块、串口转以太网设备,利用4.9152MHz校准波特率,保证数据传输准确性;
  2. 工业控制设备:PLC、传感器节点、工业机器人控制器,工业级温度范围与宽电压适配性满足车间环境要求;
  3. 嵌入式系统:STM32、ATmega等MCU的外部时钟基准,替代内部RC振荡器,提升系统时钟稳定性;
  4. 通信接口模块:CAN总线节点、SPI/I2C总线控制器,为通信协议提供精确时钟源;
  5. 低功耗便携设备:手持终端、智能传感器,1.62V低电压启动与10mA工作电流兼顾功耗与性能。

五、品牌与品质保障

星通时频(SCTF)是国内专注频率器件研发的厂商,产品通过RoHS、REACH环保认证,且针对工业级应用进行严格测试:

  • 老化测试:每批次经24小时高温老化,频率老化率≤±1ppm/年;
  • 振动测试:符合GB/T 2423.10标准,可承受10~2000Hz振动;
  • 冲击测试:符合GB/T 2423.5标准,可承受1000m/s²冲击。

此外,产品批量一致性好,满足工业设备大规模生产需求,提供1年以上质保服务。

该晶振以高性价比、强可靠性覆盖工业与消费电子的时钟需求,是串口通信、嵌入式系统等场景的优选基准器件。

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
