Full-Operation Mode
If a load is connected to an output, the corresponding
filter and amplifier turn on and remain on until the out-
put load is disconnected. In full-operation mode,
SmartSleep intelligently reduces the supply current
based on the input signal presence and output loading.
Figures 4, 5, and 6 show which portions of the
MAX9508 turn on and which remain off with different
load configurations.
When an amplifier is on, it continually checks if the load
has been disconnected by detecting if the amplifier
output is sourcing current during a horizontal line time.
If no sourcing current is detected within one horizontal
line time (approximately 64s), the load has been dis-
connected and the amplifier returns to active-detect
mode. If, at any time, the input video signal is removed,
the MAX9508 returns to standby mode.
If the SmartSleep feature is not activated and the part is
not in shutdown, the filters and amplifiers completely
turn on, regardless of whether there is a video signal at
the CVBSIN input and whether there are loads connect-
ed at the outputs.
