本型号为杭晶电子(HCI)推出的工业级固定频率时钟振荡器,核心参数聚焦工业场景的稳定性与兼容性需求:
全温范围±25ppm的稳定度,覆盖了工业现场的典型极端环境(如户外PLC、车间高低温区域),避免因温度波动导致的频率偏移——例如在-40℃低温下,输出频率偏差仍控制在±2.5kHz内,可有效防止通信丢包、FPGA时序违规等问题。
相比单端输出,LVPECL采用CLK+/-差分对,可抑制共模噪声(如电源纹波、电磁干扰),输出摆幅(典型1.2V)适配高速数字电路(如FPGA高速收发器、Ethernet PHY),支持100MHz以上的高速时钟传输,信号完整性更高。
SMD5032-6P封装为超小型设计,可节省PCB布局空间(尤其适合高密度工业控制板);3.3V供电下典型功耗≤10mW,适配电池供电或低功耗系统(如边缘网关)。
采用抗老化晶体谐振器,年老化率≤±5ppm(典型值),支持长期连续运行(工业设备通常要求10万小时以上MTBF),通过RoHS、REACH环保认证,符合工业级器件标准。
本型号采用SMD5032-6P表面贴装封装,引脚定义参考HCI官方 datasheet:
引脚编号 功能描述 注意事项 1 VCC(3.3V电源输入) 需并联100nF去耦电容滤波 2 GND(接地端) 需与PCB地平面可靠连接 3 CLK+(LVPECL正输出) 差分输出正端 4 CLK-(LVPECL负输出) 差分输出负端 5 NC(空脚) 无内部连接,避免短路 6 NC(空脚) 无内部连接,避免短路焊接要求:采用回流焊工艺(温度曲线符合J-STD-020标准),禁止手工焊接(易导致引脚虚焊/短路)。
适配PROFINET、EtherCAT、Modbus TCP等工业以太网设备(如PLC、远程IO模块),提供稳定时钟同步,保障数据传输的实时性(如EtherCAT要求时钟精度≤±50ppm)。
作为FPGA(如Xilinx Spartan-7、Altera Cyclone V)、MCU(如STM32H7系列)的主时钟源,差分输出匹配高速接口(LVDS、SerDes),避免单端时钟的信号衰减与干扰。
用于工业交换机、边缘网关、无线AP等设备的时钟参考,满足100M/1000M Ethernet的时钟同步要求(IEEE 1588协议适配)。
示波器、信号发生器等仪器的基准时钟,高精度频差确保测量结果的准确性(如示波器采样时钟要求±10ppm以内)。
本型号是工业场景下100MHz时钟需求的高性价比选择,尤其适合对宽温稳定性、差分输出有要求的设备设计。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
