outputs. If the SmartSleep feature is not activated and
the part is not in shutdown, the filters and output ampli-
fiers completely turn on, regardless of whether there is
a video signal at the CVBSIN input and whether there
are loads connected at the outputs.
SmartSleep only works with DC-coupled loads.

In standby mode, the filters and output amplifiers are
off and only the active video detect circuit is opera-
tional. Quiescent current consumption is approximately
7µA (Figure 2). The active video detect circuit checks if
sync is present on the CVBSIN signal. If no sync is
detected the device remains in standby mode.
