RENESAS 9ZXL0851EKILFT 产品概述

一、产品简介

9ZXL0851EKILFT 是瑞萨(RENESAS)推出的一款高性能时钟分配器/时钟发生器,针对Intel QPI 与 PCI Express(PCIe)体系的时钟需求优化。器件采用 VFQFPN-48(6×6 mm)封装,表面贴装,内含单路 PLL(电路数:1),支持差分输入与差分 HCSL 输出,输入/输出比率为 1:8,最大工作频率可达 400 MHz,供电电压范围 3.135V ~ 3.465V,工作温度 -40°C ~ +85°C,适用于服务器、数据中心、通信及高性能计算平台的主时钟分配。

二、主要特性

  • 单通道 PLL,1:8 分配能力,满足一对多时钟分发需求
  • 输出类型:HCSL(High-speed Current Steering Logic)差分输出,适配 Intel QPI/PCIe 时钟规范
  • 差分输入/差分输出,抗干扰能力强,信号完整性好
  • 最高输出频率:400 MHz,适合高速串行链路参考时钟
  • 供电范围:3.135V ~ 3.465V(典型 3.3V 系统兼容)
  • 环境范围:-40°C ~ +85°C,工业级温度等级
  • 封装:VFQFPN-48(6×6 mm),适用于高密度板级布局与热管理

三、应用场景

  • Intel QPI(QuickPath Interconnect)参考时钟分配
  • PCI Express(PCIe)主/从设备与桥接芯片时钟生成与分配
  • 服务器主板、北桥/南桥时钟域、通信网卡与存储控制器
  • 高速数据采集与传输系统的低抖动参考时钟源

四、设计与使用建议

  • 电源去耦:在各组电源引脚附近放置 0.1 µF 与 1 µF 低 ESR 陶瓷电容,尽量靠近封装引脚以降低供电回路阻抗。
  • 接地与散热:VFQFPN 底部常带有接地焊盘(exposed pad),建议焊接并连接到稳固的接地平面以改善热性能与信号完整性。
  • 输出终端与偏置:HCSL 输出通常需要按照芯片手册指引进行终端匹配与偏置设置(请参照瑞萨官方数据手册配置终端电阻与偏置电压)。
  • 差分布线:输出差分对采用受控阻抗(通常 100 Ω 差分)并保证差分对长度匹配、避免在差分对上出现分支或过多弯曲。
  • 布局注意:将时钟器件放置于靠近负载/接收器的中心位置以减少走线长度;时钟线尽量远离高速开关电源与大电流走线,减少干扰耦合。
  • EMI 与抖动控制:合理的地/电源平面分割和旁路设计有助于降低相位噪声与输出抖动,满足 QPI/PCIe 对低抖动的严格要求。

五、封装与可靠性

VFQFPN-48(6×6 mm)封装适合自动贴装与回流焊工艺。器件符合工业级工作温度范围,适用于长期稳定运行的服务器与通信设备。建议遵循瑞萨器件的焊接曲线与机械应力规范以确保可靠性。

六、选型与采购提示

型号:9ZXL0851EKILFT;品牌:RENESAS(瑞萨);封装:VFQFPN-48(6×6)。在选型时请确认所需输出通道数、终端方式与系统电压一致;如需更详细的引脚定义、典型应用电路与时序/锁相参数,请向瑞萨索取数据手册与评估板资料以便完成最终的硬件设计。

总结:9ZXL0851EKILFT 为面向 Intel QPI 与 PCIe 应用的高可靠性、低抖动时钟分配器,具备单通道 PLL 与 1:8 差分 HCSL 输出能力,适用于对时钟完整性有较高要求的服务器、存储与通信系统。

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
