HX3 is a family of USB 3.0 hub controllers compliant with the USB 3.0 specification revision 1.0. HX3 supports SuperSpeed (SS),Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors,and supports configuration options through pin-straps to reduce the overall BOM of the system.

HX3 includes the following Cypress-proprietary features:
Shared Link™: enables extra downstream (DS) ports for on-board connections in embedded applications
Ghost Charge™: Enables charging of devices connected to the DS ports when no host is connected on the upstream (US) port

参考设计CY4609 RDK

Thank you for your interest in the CY4609, CY4603, and CY4613 HX3 kits. HX3 is a family ofUSB 3.0 hub controller parts compliant to USB 3.0 specification revision 1.0. These parts supportLow-Speed (LS), Full-Speed (FS), Hi-Speed (HS), and SuperSpeed (SS) peripherals.

The CY4609 Reference Design Kit (RDK) is a small form-factor, ready-to-use hub reference design.

The CY4603 Development Kit (DVK) provides the flexibility to configure and evaluate all HX3 features.

The CY4613 DVK implements advanced features, such as Shared Link™ and ACA-Dock.This document is the common user guide for the three HX3 kits, which are based on three differentHX3 USB 3.0 hub controller parts.

The CY4603, CY4609, and CY4613 kits are intended for use as a development platform forhardware or software in a laboratory environment. The board is designed as an open system, whichdoes not include a shielded enclosure. This may cause interference to other electrical or electronicdevices in close proximity. In a domestic environment, these products may cause radio interference.

In such cases, you may be required to take adequate preventive measures. In addition, theseboards should not be used near any medical equipment or RF devices.

Attaching additional wiring to these products or modifying the product operation from the factorydefault may affect their performance and cause interference with other apparatus in the immediatevicinity. If such interference is detected, suitable mitigating measures should be taken.
