General Description
The MIC2551A is a single chip transceiver that complies with the physical layer specifications of the Universal Serial Bus (USB) 2.0. It supports both full speed (12Mbps) and low speed (1.5Mbps) operation and introduces superior edge rate control, producing crisper eye diagrams. This in turn, eases the task of passing USB compliance testing. A unique, patented, dual supply voltage operation allows th.

General Description
The MIC2551A is a single chip transceiver that complies with the physical layer specifications of the Universal Serial Bus (USB) 2.0. It supports both full speed (12Mbps) and low speed (1.5Mbps) operation and introduces superior edge rate control, producing crisper eye diagrams. This in turn, eases the task of passing USB compliance testing. A unique, patented, dual supply voltage operation allows the MIC2551A to reference the system I/F I/O signals to a supply voltage down to 1.6V while independently powered by the USB VBUS. This reduces system operating current and allows the system to operate at its core voltage without additional buffering logic. MIC2551A-2.5 is differentiated from MIC2551A by a smaller space saving MLF™ package (2.5mm × 2.5mm) and ±15kV ESD protection which eliminates the need for separate ESD protection devices on the D+, D- data lines. Data sheets and support documentation can be found on Micrel's web site at www.micrel.com.
