Ceramic Resonators Ease Space Constraints when Designing High-Speed USB into Handsets

With an increasing number of consumers carrying and transferring large multimedia files such as MP3 and MPEG into their portable devices, leading consumer electronics manufacturers are rushing to design HS-USB into their products.  Any designer looking at adding HS-USB will immediately run into the common hurdles of optimizing size, power, and cost.  Currently, few application processors and baseband processors integrate HS-USB due to the difficulty of integrating the PHY onto small process technologies, so designers must add a separate HS-USB controller to their designs.  One large component that always accompanies a HS-USB peripheral controller is a crystal.  This article discusses the use of small foot-print, price-comparable ceramic resonators that make designing HS-USB into space-constrained applications a less daunting task.
