recorders, VCRs, home theater systems with
clock feature, HTiB (home theater in a box),
personal video recorders (PVRs), set-top boxes
and other applications that require a compact,
integrated solution, while keeping system cost as
low as possible. The design focus of this system is
on 2 key areas: a standby management feature for
low power consumption and an embedded real-
