The HX3 has three evaluation kits available. The CY4609 reference design supports only ganged power switching mode to the downstream ports. The CY4603 is a design verification kit. It is used to support the individual or ganged power switching mode, pin-strap GPIOs, and status indicator for downstream ports. The third kit is the CY4613, which is used to verify the shared link and ACA dock mode in the upstream port.
