cypress公司的CYUSB330x, CYUSB331x, CYUSB332x和CYUSB230x系列是 HX3 USB 3.0集线器控制器,符合USB3.0 规范版本1.0,有端口上均支持超高速(SS),高速(HS),全速(FS)以及低速(LS)功能.器件包含集成的终端电阻、上拉和下拉电阻,并支持通过引脚设置(pin-strap)的各个配置选项,以减低硬件系统的材料清单(BOM).主要用在独立集线器,PC 和平板电脑主板,基座,手持设备支架,监视器,数字电视,机顶盒和打印机.本文介绍了HX3 USB 3.0集线器主要特性,框图,以及HX3 USB 3.0集线器参考设计CY4609主要特性,框图和电路图.

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

HX3 USB 3.0集线器参考设计CY4609

CY4609 is an easy-to-use Reference Design Kit to evaluate the USB-IF Certified CYUSB330x family of HX3 USB 3.0 hub controllers. The kit can be used as a reference design for standalone USB 3.0 hub application. This kit comes integrated with the required components and the Blaster Plus software utility. Blaster Plus is a GUI based Cypress software tool to change the configuration parameters of HX3.
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.

HX3 USB 3.0集线器参考设计CY4609硬件包括:

■ CYUSB3304-68LTXC hub controller
■ 5-V DC supply jack to connect the 5-V/4-A power adapter provided as part of the kit
■ Two DC-DC power regulators to provide 3.3-V and 1.2-V power supply
■ Four USB 3.0 downstream ports and a USB 3.0 upstream port
■ Configuration mode select jumpers (J7 and J8)
■ Onboard 16-KB I2C EEPROM to store configuration data and hub controller firmware
■ Power LED (PWR) and Hub Suspend Status LED (SUSP)
■ Current measurement jumper (J2)
