HCI CO53D6-156.250-33KDTSN 156.25MHz LVDS晶振产品概述

一、产品核心定位与典型应用场景

杭晶(HCI)CO53D6-156.250-33KDTSN是一款针对高速数字通信、工业控制及消费电子领域设计的工业级LVDS输出晶振。其156.25MHz基准频率为行业标准时钟源,精准适配千兆/万兆以太网、PCIe 2.0/3.0、高清视频传输等场景的核心芯片时钟需求,尤其适合对宽温稳定性、低噪声有要求的设备。

典型应用包括:

  • 工业控制:PLC、运动控制器、工业主板的核心时钟,满足-40℃~+85℃宽温环境下的高精度要求;
  • 网络通信:千兆/万兆以太网交换机、路由器的PHY芯片参考时钟,保障数据传输误码率≤1e-12;
  • 消费电子:高清机顶盒、智能电视的视频处理芯片时钟,提升画面传输稳定性;
  • 车载电子(扩展适配):车载信息娱乐系统的高速接口时钟(若需车规级需确认衍生型号)。

二、关键电气性能参数解析

该晶振的核心参数围绕“高精度、低噪声、抗干扰”设计,具体如下:

1. 频率精度与稳定度

  • 标称频率:156.25MHz(行业标准时钟,对应PCIe 2.0、10GBASE-T等协议);
  • 常温频差:±10ppm(25℃环境下,满足大多数高速电路的同步要求);
  • 全温稳定度:±25ppm(-40℃~+85℃范围内,避免温变导致的时钟偏差)。

2. LVDS输出特性

采用低电压差分信号(LVDS)输出,优势显著:

  • 输出摆幅:≈350mV(低功耗,比LVPECL减少50%功耗);
  • 差分阻抗:100Ω(匹配传输线,减少信号反射);
  • 抗干扰:差分信号抑制共模噪声,传输距离可达10米以上(适合板间时钟传输)。

3. 电源与功耗

  • 工作电压:3.3V±5%(兼容2.97V~3.63V,适配主流主板电源);
  • 典型功耗:≈10mW(低功耗设计,适合电池供电或散热受限设备)。

4. 相位噪声

典型相位噪声为:

  • 1kHz offset:-120dBc/Hz;
  • 10kHz offset:-130dBc/Hz;
  • 100kHz offset:-140dBc/Hz;
    低相位噪声可减少时钟抖动对高速数据传输的影响。

三、封装与机械设计特性

1. 封装规格

采用SMD5032-6P小型化贴片封装,尺寸为5.0mm×3.2mm×1.2mm(长×宽×高),节省PCB空间,适合高密度设计设备。

2. 引脚定义(行业标准)

引脚 功能 备注 1 VCC 3.3V电源输入 2 GND 接地 3 NC 空脚(无连接) 4 OUT- LVDS差分输出负端 5 OUT+ LVDS差分输出正端 6 GND 接地(双GND增强屏蔽)

3. 贴装兼容性

符合IPC-J-STD-001标准,支持回流焊工艺(峰值温度260℃±5℃,时间≤10秒),适合自动化批量生产。

四、环境适应性与可靠性表现

1. 宽温工作能力

覆盖-40℃~+85℃工业级温度范围,可在严寒(如北方户外基站)或高温(如工业控制柜)环境下稳定运行。

2. 可靠性测试

杭晶对该产品进行了严格的可靠性验证:

  • 振动测试:10g~2000Hz(符合MIL-STD-202 Method 201);
  • 冲击测试:1000g(1ms半正弦波,符合MIL-STD-202 Method 213);
  • 老化测试:1000小时老化后频率漂移≤±5ppm(保障长期稳定性);
  • 湿度测试:85℃/85%RH环境下1000小时,性能无衰减。

3. 环保认证

符合RoHS 2.0及REACH标准,不含铅、镉等有害物质,满足全球市场环保要求。

五、工程选型与设计注意事项

1. 频率匹配

需确认目标芯片的时钟输入频率是否为156.25MHz(如Intel I210千兆网卡、Broadcom BCM54680万兆PHY)。

2. 输出端匹配

LVDS输出需在接收端并联100Ω差分终端电阻(靠近接收芯片引脚),匹配传输线阻抗,减少信号反射。

3. 电源滤波

晶振电源端建议串联10Ω~22Ω电阻,并联0.1μF陶瓷电容+10μF电解电容,过滤电源噪声。

4. PCB布局要点

  • 晶振靠近接收芯片,减少时钟线长度;
  • 时钟线采用差分微带线,阻抗控制100Ω;
  • 晶振下方及周围铺地,增强屏蔽;
  • 避免时钟线与高频信号线平行布线(减少串扰)。

该产品凭借杭晶的工业级制造工艺,在精度、稳定性及抗干扰性上均能满足中高端设备的时钟需求,是高速数字电路设计的可靠选择。

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.
