General 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 con-
trol to produce crisper eye diagrams. As a result, the task of
passing USB compliance testing is made easier.
A unique, 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 V
core voltage without addition of buffering logic and also
reduce system operating current.
