... As a result, the task of passing USB compliance testing is made easier. www.DataSheet4U.com A unique, patented, dual supply voltage operation allows the MIC2550A to reference the system I/F I/O signals to a supply voltage down to 2.5V while independently powered by the USB V . This allows the system interface to operate at its ...

... MIC2550A PCB Layout Recommendations Although the USB standard and applications are not based in an impedance controlled environment, a properly designed PCB layout is recommended for optimal transceiver perfor- mance. The suggested PCB layout hints are as follows: • Match signal line traces (VP/VM, D+, D–) to ...
