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, which ease 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 V

core voltage without addition of buffering logic and also

reduce system operating current.
