3. Terms You Will Hear Today
USB 3.0
A USB standard that supports both 5-Gbps SuperSpeed (SS) and legacy USB 2.0
Host, Device, Hub
The Host (e.g., a PC) directs data traffic and distributes power over the USB bus
The Device (e.g., a hard disk drive) is a peripheral on the USB bus
The Hub (e.g., in a notebook PC docking station) directs data traffic between a USB Host and multiple USB Devices
USB 3.0 Physical Layer (PHY)
The circuitry that transmits and receives USB data
Contains both a SS PHY and a USB 2.0 PHY
Upstream (US) Port, Downstream (DS) Port
The Upstream Port of a Hub connects to a Host or to a Downstream Port of another Hub
The Downstream Port of a Hub connects to a Device or to an Upstream Port of another Hub

4. HX3 Terms Shared Link™ Ghost Charge™ HX3 Blaster Plus™
A proprietary Cypress feature that enables a USB 3.0 port to be split into an internal1 SS port and a standard USB 2.0 port
USB 3.0 port = 5-Gbps internal SS port Mbps standard USB 2.0 port
Four USB 3.0 ports = four internal SS ports + four standard USB 2.0 ports = eight total ports
Ghost Charge™
A proprietary Cypress feature that enables battery charging on HX3’s DS ports
Enables a portable Device to be charged without a Host (e.g., PC) connected to the US port
HX3
Cypress’s USB-IF certified four-port USB 3.0 Hub controller
Supports Shared Link and Ghost Charge
Supports BC v1.2 and the Apple Charging Standard on all DS ports
Has a dedicated Transaction Translator (TT) per DS port, eliminating sharing of FS bandwidth among DS ports

5. Design Problems Engineers Face
USB interoperability is difficult to ensure
Not all USB products are certified, causing interoperability problems
The installed base has products dating to1996, making exhaustive interoperability testing difficult, even for fully certified products
The number of USB 3.0 ports on PCs is limited
Most new PCs are equipped with only one or two USB 3.0 ports, not enough for the growing number of USB 3.0 peripherals
USB 3.0 presents significant challenges to signal quality
Long PCB traces and cables degrade USB signal quality dramatically at 5 Gbps
Most ICs do not compensate for this degradation, leading to USB-IF compliance failures
USB charging must support multiple standards in practice
A USB port is commonly used for charging, but many different proprietary charging standards exist (e.g., Apple Charging Standard)
HX3 by Cypress solves these problems
HX3 is proven to work with all known Host controllers, Device classes and OSs by repeated testing at every USB plug-fest
HX3 uses Shared Link to double the number of USB ports, creating eight ports from a four-port Hub
HX3 drives 2x longer PCB traces versus the competition while maintaining USB compliance
HX3 supports all common USB charging standards, including BC v1.2, the Apple Charging Standard, Ghost Charge and ACA-Dock
HX3 can provide compelling features for your next Hub design
Most customers need longer PCB traces to meet their industrial design requirements; Most customers need longer PCB traces to meet their industrial design requirements
USB charging implementation is not universal
HX3 is interoperable with 6 Hosts, 3 operating systems, and 74 Devices…
(Custom firmware helps flexibility) 5

6. HX3’s Shared Link Splits 1 Port into 2
Use Shared Link to double the number of USB ports
Shared Link allows each USB 3.0 Downstream Port to be split into an internal SS port and a standard USB 2.0 port
Example: Shared Link Provides Six USB Ports in a Notebook
