USB 2.0 brought a significant increase in bandwidth over the 1.1 specification. Offering 40x more bandwidth, it increased the importance of a good PCB design and a careful selection of components surrounding USB chips such as Cypress’s FX2LP. This application note presents a host of USB design topics that apply to any USB device at any speed, but especially to the higher speeds of USB 2.0. Although the discussions are specific to Cypress devices, they also should be helpful in any USB peripheral design.
