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

Last Updated:

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.
