Cypress EZ-USB HX3 USB 3.0 hub controller

Cypress Semiconductor has announced the EZ-USB HX3 USB 3.0 hub controller, certified by the USB Implementers Forum (USB-IF) for the SuperSpeed USB 5 Gbps standard.

The product offers robust interoperability, extensive charging support and full configurability, making it suitable for docking stations, monitors, ultrabook devices, digital TVs, set-top boxes, printers and servers.

The versatile hub controller offers a Ghost Charging feature for charging of devices without a host, and supports the USB-IF Battery Charging v1.2 specification and charging of Apple devices. It offers an Accessory Charger Adaptor Dock (ACA-Dock) feature, which enables upstream charging for portable devices with a USB On-The-Go (OTG) host. It includes a Shared Link feature that enables up to eight downstream ports, allowing products such as docking stations and desktop monitors to connect with more USB peripherals using a single four-port hub.

The product offers full configurability via I2C EEPROM, I2C Slave and GPIO options, allowing designers to configure PHY drive strength, the number or downstream ports, power switch polarity, LED indicators and more. It consumes only 735 mW with all ports in operation at SuperSpeed data rates.
