... MIC2550 General Description The MIC2550 is a single-chip transceiver that complies with the physical layer specifications for Universal Serial Bus (USB). The MIC2550 supports full-speed (12Mb/s) dual supply volt- age operation (patent pending) and low-speed (1.5Mb/s) operation. A unique dual supply voltage operation allows the MIC2550 to reference the system I/F I/O signals to a supply voltage down to 2 ...
