The West Bridge® Antioch™ device is a USB and mass storage peripheral controller that is a perfect fit for handset applications. The baseband or applications processors in handset systems may need to use an integrated full-speed USB transceiver at times, and switch to the West Bridge Antioch device for high-speed USB operations. This requires the use of a USB switch. This application note discusses the implications of adding a USB switch with West Bridge Antioch and provides the PCB layout recommendations to avoid degradation of signal integrity.
