9DB403DGLFT 为瑞萨(RENESAS)出品的一款高速 PCI‑Express(PCIe)扇出缓冲器(zero‑delay buffer)。器件集成锁相环(PLL),支持单路输入到四路差分输出的 1:4 分配,输入为 HCSL 差分,输出可提供 HCSL 或 LVDS 差分信号。器件工作频率最高可达 400MHz,供电电压范围为 3.135V ~ 3.465V(典型接近 3.3V),工作温度为 0°C ~ 70°C,封装为表面贴装 TSSOP‑28,适用于商用温度等级的系统设计。
适用于 PCIe 时钟分配(主板、扩展卡、交换机)、高性能服务器与存储设备、FPGA/ASIC 时钟分配、以及其他需低抖动、低延迟差分时钟分配的高速串行链路系统。
为保证时钟完整性与最低抖动,应遵循以下实务建议:
选择 9DB403DGLFT 时,应重点确认目标系统对频率(≤400MHz)、差分接口类型(HCSL/LVDS)、工作温度与供电电压的匹配。若需更宽温度范围、不同输出通道数或更低抖动性能,可比较同类零延迟缓冲器或其他厂商对应产品,关注抖动、输出驱动能力、使能/失能控制及功耗参数。
器件在不同输出标准间的使用细节(例如是否需要外部偏置、AC 耦合或特定终端)请依据瑞萨官方数据手册与接收端规范实施。新设计建议先在评估板上验证时钟完整性、抖动与相位关系,再进行系统级布局。
9DB403DGLFT 为面向 PCIe 等高速差分时钟分配的零延迟扇出缓冲器,集成 PLL、1:4 差分输出、支持 HCSL/LVDS,适合需要低延迟、集中时钟管理的商用电子系统。设计时请结合瑞萨数据手册与目标接口规范,按 PCB 布局与终端要求完成实现,以确保最佳时序与信号完整性。

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.
