FSUSB42UMX-TP 产品概述

一、产品简介

FSUSB42UMX-TP 是 TECH PUBLIC (台舟电子) 推出的一款双向低功耗高速 USB 2.0 模拟开关,专为 USB Type‑C 系统中的 USB 2.0 DP/DM 差分数据线提供集成切换与隔离保护。器件可配置为双 2:1 或 1:2 开关结构,支持双通道独立控制,能够在高速差分信号传输中保持良好的信号完整性与通道间隔离。

二、主要功能特性

  • 双向模拟通道,支持双 2:1 或 1:2 配置,适用于 USB Type‑C 切换场景。
  • 真正的断电隔离:即使 COM+/‑ 覆盖 VCC,也仅有极少电流回流到电源,减少系统异常状态下的干扰与功耗。
  • 适配 USB 2.0 高速(480 Mbps),低比特间偏斜与高通道间噪声隔离,保持差分信号对称性。
  • 低导通电阻,导通电阻(Ron)典型值 1.5 Ω,保证高速信号幅度和上/下沿完整性。
  • 低导通电容(Con)约 7 pF,带宽高达 550 MHz,适合 480Mb/s 差分信号传输。
  • 快速开关响应,导通/关闭时间 (ton/toff) 约 200 ns,满足 USB 切换与热插拔要求。
  • 工作电压范围 1.5 V ~ 5.5 V,工作温度范围 -40 ℃ ~ +85 ℃ 。

三、关键电气参数

  • 开关结构:2:1,通道数:2(双端口)
  • 导通电阻(Ron):1.5 Ω(典型)
  • 导通电容(Con):7 pF(典型)
  • 导通/关闭时间:ton = 200 ns,toff = 200 ns(典型)
  • 带宽:550 MHz(典型)
  • 工作电压:1.5 V~5.5 V
  • 工作温度:-40 ℃~+85 ℃

四、信号完整性与隔离能力

FSUSB42UMX-TP 针对 USB 2.0 差分高速线路优化,低 Ron 与低 Con 的组合降低了插入损耗与对称失配,带宽 550 MHz 足以支持 480 Mb/s 的数据率而不引起明显的频率衰减。器件在通道间提供高噪声隔离和低比特间偏斜,确保差分对的时序一致性与眼图质量,适合对信号完整性要求严格的消费电子与外设产品。

五、封装与应用场景

  • 封装:QFN-10L (1.4 × 1.8 mm),小尺寸适合空间受限的移动设备与接口控制板。
  • 典型应用:USB Type‑C 切换控制、智能手机/平板/笔记本的 USB 2.0 路由与保护、电缆/扩展坞、USB 集线器、车载娱乐系统与各类主控板的高速数据线开关与隔离方案。

六、使用建议与注意事项

  • 在设计 PCB 时尽量保持差分线短直,配对阻抗一致,靠近器件做去耦和地平面,以充分发挥器件的带宽与隔离性能。
  • 对于热插拔或多供电域场景,合理安排控制逻辑与 VCC 优先级以避免切换瞬态造成的干扰。FSUSB42UMX-TP 在 VCC 覆盖情况下提供低回流特性,但系统设计仍应考虑其他保护(如 TVS)以应对极端瞬态。
  • 根据系统供电电压选择合适的驱动与控制电平,器件支持 1.5 V~5.5 V 宽电压域。

FSUSB42UMX-TP 以其低阻抗、低电容、高带宽与断电隔离特性,为 USB Type‑C 系统中 USB 2.0 差分线路提供可靠的切换与保护方案,是需要在有限空间内实现高信号完整性与低功耗隔离的理想元件。

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
