CY4609: 4-Port USB 3.0 Hub

Summary

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 that conform to USB 3.0 and BC v1.2 specifications. The ports 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; it can support both slave and master modes. On the RDK, an EEPROM is connected to the hub controller on this interface to store the configuration data and firmware.
