USB 3.0 集线器控制器系列框图Thank you for your interest in the HX3 kits (CY4609 and CY4603). These kits are designed to be easy to use, and they showcase the features of Cypress’s HX3 USB 3.0 hub controller parts. HX3 is a family of USB 3.0 hub controller parts compliant to USB 3.0 specification revision 1.0. These parts support Low-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 the HX3 features. This document is the common user guide for the two HX3 kits, which are based on two different HX3 USB 3.0 hub controller parts.USB 3.0 集线器控制器主要特性:图2.CY4609板外形图图3.CY4603板外形图CY4609 RDK硬件设计The CY4609 RDK is based on the CYUSB3304-68LTXC hub controller. It is a small form factor hardware supporting four USB 3.0 downstream ports. All of these downstream ports conform to USB 3.0 and BC v1.2 specifications. They also support Ghost Charging and emulate Apple charging. The upstream port is implemented using a USB 3.0 micro-B connector.The RDK is shipped with a 5-V AC-DC adapter with a current rating of 4 A. However, the hardware is designed to support operation with an AC-DC adapter with up to a 6-A current rating.The CYUSB3304-68LTXC hub controller is clocked using a 26-MHz crystal on the board.The HX3 hub controller supports an I2C communication interface, and it can support both slave and master modes. On the RDK, an EEPROM is connected to the hub controller on this interface to store configuration data and firmware.CY4609 RDK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 for storing configuration data and hub controller firmware■ Two LEDs: Power LED (PWR) and Hub Suspend Status LED (SUSP)■ Current measurement jumper (J2)图4. CY4609 RDK框图The CY4603 DVK supports four downstream ports, which are terminated as USB 3.0 type-A connectors. All these downstream ports conform to the USB 3.0 and BC v1.2 specifications. They also support Ghost Charging and emulate Apple charging. Each downstream port is controlled using a power switch, which allows monitoring an over-current situation on each downstream port and shutdown of the ports with an over-current condition selectively.The CYUSB3314-88LTXC hub controller is clocked using a 26-MHz crystal. More details about the crystal specification are available in the HX3 datasheet. The DVK is powered using a 5-V AC-DC adapter. The DVK is shipped with a 5-V AC-DC adapter with a current rating of 4 A. However, the power supply tracks on the DVK hardware are designed to support up to 8 A of input current. The DVK contains two onboard DC-DC regulators to provide a 3.3-V and 1.2-V power supply to the HX3 hub controller. A 5-V input from the AC-DC adapter is directly passed to the downstream ports via the power switches.The HX3 hub controller supports the I2C communication interface, and it can support both slave and master modes. On the DVK, an I2C EEPROM is interfaced to the hub controller to store configuration data and firmware, with the hub controller acting as the I2C master.图5.CY4603硬件框图图6. CY4603 RDK电路图(1)图7.
