Introduction
Cypress’s TetraHub
is a high-performance self-powered Universal Serial Bus (USB) 2.0 hub. The Tetra architecture provides
four downstream USB ports, with a Transaction Translator (TT) for each port, making it the highest-performance hub possible.
This single-chip device incorporates one upstream and four downstream USB transceivers, a Serial Interface Engine (SIE), USB
Hub Controller and Repeater, and four TTs. It is suitable for standalone hubs, motherboard hubs, and monitor hub applications.
Being a fixed-function USB device, there is no risk or added engineering effort required for firmware development. The developer
does not need to write any firmware for their design. The CY4602 Tetrahub USB 2.0 4-port Hub Reference Design Kit provides
all materials and documents needed to move rapidly into production. The reference design kit includes board schematics, bill of
materials, Gerber files, Orcad files, key application notes, and product description.

The SIE allows the CY7C65640 to communicate with the USB host through the USB repeater component of the hub. The SIE
handles the following USB bus activity independently of the Hub Control Block:
Bit stuffing/unstuffing
Checksum generation/checking
ACK/NAK/STALL
TOKEN type identification
Address checking.
