SI5351B-B-GMR 产品概述
一、产品概述
SI5351B-B-GMR 是一款面向系统时钟生成的集成器件，属于 MultiSynth™ 系列，封装为 20 引脚 QFN（4×4 mm，带裸露焊盘），由 Skyworks Solutions 出货（包装：卷带 TR）。该器件集成 PLL 与分频功能，支持晶体输入并提供 LVCMOS 电平输出，单通道/多路比例可达输入:输出 1:8，最高输出频率可达 200 MHz，适合替代固定晶振或简单相位锁定时钟源的应用。
二、主要特性
- 集成 PLL 的可编程时钟发生器
- 晶体（XTAL）输入，简化系统时钟参考源
- LVCMOS 电平输出，逻辑兼容性好
- 支持分频器功能（无内部倍频器），灵活生成多路频率
- 供电电压范围宽：1.71 V ~ 3.6 V
- 工作温度范围：-40 °C ~ 85 °C
- 封装：20‑VFQFN（裸露焊盘），供应商器件封装标识 20‑QFN（4×4）
- 包装形式：卷带（TR），状态：在售
三、电气与环境参数（概览）
- 最大输出频率：200 MHz（LVCMOS）
- 差分输入/输出：无 / 无（仅单端 LVCMOS）
- 电源与功耗：供电 1.71–3.6 V，建议在布局中增加去耦电容以降低噪声影响
- 环境：商业/工业级温度（-40 °C ~ 85 °C）
四、封装与布局注意事项
- 裸露焊盘需可靠焊接以保证散热与接地完整性；建议遵循厂商推荐的焊盘设计和回流曲线
- XTAL 布线应尽量缩短，靠近晶振输入脚并加局部地平面隔离以降低杂散耦合
- 电源引脚旁放置足够的去耦电容（近距离），并用合理的电源平面分割模拟与数字噪声
- 输出走线考虑终端匹配与负载（LVCMOS），避免长线反射和串扰
五、典型应用场景
- 嵌入式系统与 MCU/FPGA 的时钟源
- 通信设备和数据采集前端的本地时钟生成
- 多频率时钟需求的测试与测量设备
- 需要替换多个固定频率晶振以节省系统空间与库存的产品
六、选型与订购提示
- 型号：SI5351B-B-GMR，品牌：SKYWORKS，基本产品编号：SI5351
- 包装：卷带（TR），便于贴片生产线使用
- 选型时确认输出频率、通道数量与电压兼容性，并参考厂商参考设计与器件数据手册进行寄生参数校验与布局验证。
如需原理图接线示例、晶体规格建议或 PCB 布局参考图，可提供特定应用场景以便给出更具体的设计建议。

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.
