MIC2551A
USB Transceiver
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
BUS
. This allows the system interface to operate at its
core voltage without addition of buffering logic and also
reduce system operating current.
