摘要

TUSB1142 是一款具有 1:2 多路信号分离器或 2:1 多路复用器功能的 10Gbps USB 3.2 线性转接驱动器,适用于 USB-C® 应用。TUSB1142 用于驻留在主机和 USB-C 插座之间或 USB 器件和 USB-C 插座之间。TUSB1142 支持第 2 代 USB 3.2 (10Gbps) 和第 1 代 USB 3.2 (5Gbps) 以及 USB 3.2 低功耗状态(断开、U1、U2 和 U3)。

TUSB1142 具有自适应接收器均衡 (AEQ) 功能。AEQ 功能会自动确定 TUSB1142 和插入 USB 连接器的 USB 器件之间的最优 ISI 补偿设置,从而提高互操作性。

TUSB1142 由 3.3V 单电源供电运行,并采用 40 引脚 WQFN 封装。
