Description

The MIC2550A is a single-chip transceiver that complies with the physical layer specifications for Universal Serial Bus
(USB).
The MIC2550A supports full-speed (12Mbps)  and low-speed (1.5Mbps) operation and introduces superior edge rate control to produce crisper eye diagrams. As a result, the task of passing USB compliance testing is made easier. Aunique, 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 VBUS. MIC2550A allows the system interface to operate at its core voltage without addition of buffering logic and also reduce system operating current.
