AN5044 - EZ-USB Hubs(CY7C656XX) PCB Design Recommendations
AN5044 presents recommendations for designing with the Cypress Semiconductor CY7C65640A, CY7C65630, and CY7C65620 components. Techniques for high-speed design must be applied to circuits using these components. Due to the packaging and high performance characteristics of the hub chips, it is recommended that applications consider the PCB thermal design.
Compatible development kits include EZ-USB HX2LP(TM) USB 2.0 2-Port Hub Reference Design Kit CY4605 and EZ-USB HX2LP(TM) USB 2.0 4-Port Hub Reference Design Kit CY4606.
The appnote applies to
Tetrahub, CY7C65640A as well.
