Today's intellectual property (IP) choices for the Universal Serial Bus (USB) cover many different types of interfaces for use in a wide variety of applications, including portable consumer products. Power consumption and small form factors are thus key issues. System-on-a-Chip (SoC) designers must also consider new requirements imposed by smaller technology nodes, especially for the USB PHY. This paper provides insights into dealing with these issues and profiles the USB IP choices available from Synopsys.
