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) Design Problems 5

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 USB 3.0 Port Split into SS Port and Standard USB 2.0 Port Notebook PC Motherboard USB 3.0 Camera USB 2.0 WiFi Module Standard USB 2.0 Port SS (internal) 4 USB 2.0 2 USB 3.0 6 PC Chipset USB 3.0 Host DS4 6 DS1 USB 3.0 Internal SS Port 6 HX3 US 6 DS2 USB 3.0 DS3 USB 3.0 SSRX- SSRX+ SSTX- SSTX+ D- D+ 6 2 USB 2.0 SS (internal) 4 USB 3.0 Card Reader HX3 USB 3.0 Port HX3’s Shared Link feature creates eight Downstream Ports from a four-port USB 3.0 Hub Cypress Solution 6
