General Description
The MIC2551 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. It is also designed to operate
down to 1.6V in order to be compatible with lower system
voltages of most mobile systems.
