TetraHubTM USB 4-Port Hub Reference Design CY4602

USB 4-Port Hub

The TetraHubTM is the highest performance USB hub solution available. Cypress offers a complete reference design for developing a fixed function 4-port USB Hub that is production ready and USB compliant.

This single chip design is based on the CY7C65640-LFC, offering a space saving and cost effective package. Because it is USB compliant it is fully backward compatible with USB systems. It provides for up to four downstream ports, and supports High Speed, Full Speed and Low Speed traffic. No firmware development is required for this design, thereby reducing design risk and time-to-market.

Our Reference Design Kits include a fully functional demonstration board as well as all of the design materials you will need to expedite the development of your custom product. Cypress provides faster time-to-market and the lowest overall system cost with our TetraHub Reference Design.

Transaction Translators

When compared to a USB hub, a USB hub functions more like a host controller, using “transaction translators” to convert Low and Full Speed traffic to High Speed, instead of just passing it through. With a single transaction translator, bandwidth must be shared among downstream Low and Full Speed devices. Cypress’s unique design, integrating four transaction translators, allows us to provide the highest performing hub chip on the market, supporting the full bandwidth for every downstream Low and Full Speed device.
