9DB433AGILFT 产品概述
一、概述
9DB433AGILFT 是瑞萨（RENESAS）推出的一款面向高性能串行链路和系统时钟分配的零延迟扇出缓冲器（Zero Delay Buffer, ZDB）。器件支持单输入四输出，工作电压 3.3V，最高工作频率可达 166MHz。内置锁相环（PLL）实现输入时钟与输出时钟的相位对齐，适用于 PCI-Express（PCIe）及其它高速接口的时钟分配和整形。
二、主要功能特性
- 单输入、四路输出结构，简化板级时钟分配拓扑。
- 内置 PLL，实现零延迟（输出与输入保持相位同步）和多路驱动能力。
- 支持扩展频谱（Spread Spectrum）功能，便于系统 EMI 优化。
- 低抖动时钟重整/清抖（clock cleaning），改善输入抖动并提供稳定的输出时钟。
- 含输出使能/关断控制，便于功耗管理与热插拔场景。
- 封装为 28-TSSOP，适合中高密度 PCB 布局与量产装配。
三、典型规格要点
- 输入通道：1；输出通道：4。
- 工作电压：3.3V。
- 工作频率范围：可支持至 166MHz（具体性能与抖动指标请参见器件说明书）。
- 相位关系：零延迟/相位对齐；输出可与输入同步锁定。
- 控制功能：输出使能/关断与扩展频谱配置（由引脚或寄存器控制，详见规格书）。
四、典型应用场景
- PCIe 主板与扩展卡的时钟扇出与分配。
- FPGA/ASIC 时钟树驱动与时钟清洗。
- 服务器、存储与网络设备的多路时钟分配。
- 需 EMI 管控的系统（利用扩展频谱功能降低电磁辐射）。
五、封装与选型建议
器件采用 28-TSSOP 封装，适用于自动贴装生产。选型时应参考系统频率、输出驱动能力、抖动容限以及是否需扩展频谱功能；若需多通道或更高频率，可考虑同系列或替代型号。建议下载并参照瑞萨官方数据手册获取完整引脚分配与电气特性。
六、设计注意事项
- 电源去耦：芯片电源引脚附近放置足够的陶瓷电容以抑制噪声。
- 布线：输出走线需控制阻抗并尽量匹配长度，避免不必要反射。
- PLL 锁定：关注上电序列与锁相时间，必要时在系统中加入复位/启用序列。
- EMI/散热：启用扩展频谱可降低 EMI；高密度应用关注封装散热与板上热管理。
- 引脚保护：按数据手册处理输出使能及 I/O 过压/ESD 情况。

Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
