AN222944 HX3PD硬件设计指南和检查表
硬件（英文名Hardware）是计算机硬件的简称（中国大陆及香港用语，台湾叫作:硬体），是指计算机系统中由电子，机械和光电元件等组成的各种物理装置的总称。这些物理装置按系统结构的要求构成一个有机整体为计算机软件运行提供物质基础。
简而言之，硬件的功能是输入并存储程序和数据，以及执行程序把数据加工成可以利用的形式。从外观上来看，微机由主机箱和外部设备组成。主机箱内主要包括CPU、内存、主板、硬盘驱动器、光盘驱动器、各种扩展卡、连接线、电源等；外部设备包括鼠标、键盘等。

EZ-USB HX3PD Hardware Design Guidelines and Checklist
Authors: Hena Thampy, Vetrivel Prakasam
Associated Part Family: CYUSB4347, CYUSB4357
This application note provides the hardware design and PCB layout guidelines for EZ-USB® HX3PD, a high-performance
USB 3.1 Gen 2 (10 Gbps) Type-C Hub with Power Delivery capability. These guidelines help to ensure best performance
with respect to signal integrity and full electrical compliance with the USB 3.1 Gen 2 Specification. A schematics and layout
review checklist is provided in the end, which consolidates all the important points to be considered while designing with
HX3PD.

Introduction
EZ-USB HX3PD is a 7-port USB 3.1 Gen 2 (10 Gbps) Type-C Hub with Power Delivery (PD) capability, recommended
for applications such as standalone PD Hub, notebook PC docks, monitor docks, and dongle applications. It is a one-
chip solution, integrating a USB 3.1 Gen 2 10 Gbps Hub, two-port PD Controller, and a Dock Management Controller
(DMC). HX3PD expands a single upstream (US) Type-C PD port into multiple downstream (DS) ports. It supports
SuperSpeed USB 10 Gbps, SuperSpeed USB, Hi-Speed (HS), Full Speed (FS), and Low-Speed (LS) functionality. In
addition, it provides a complete Type-C and USB PD Port Controller solution in the US and one DS port. HX3PD
f SPI interface, Serial communication block, and GPIOs.

DS1: Type-C, PD, and SuperSpeed USB 10 Gbps port
DS2 and DS3: Type-C, non-PD, SuperSpeed USB 10 Gbps ports
DS4 and DS5: Type-A SuperSpeed USB 10 Gbps ports
DS6 and DS7: Type-A USB 2.0 ports
Hub Controllers: HX3PD consists of two Hub Controllers: a SuperSpeed USB 10 Gbps Hub Controller and a USB
2.0 Hub Controller. The former supports SuperSpeed USB 10 Gbps Hub functionalities such as full-duplex data
transmission and link power management (U0, U1, U2, and U3 states). The USB 2.0 Hub Controller supports LS,
FS, and HS functionalities such as multiple transaction translators (TTs) and USB 2.0 link power management (L0,
L1, L2, and L3 states).
