MAX9512ATE+T
Video Filter Amplifier with SmartSleep and Y-C Mixer Circuit
General Description
The MAX9512 video filter amplifier with SmartSleep and
Y/C mixer is ideal for portable media players (PMPs),
portable DVD players, and set-top boxes (STBs). The
inputs can be directly connected to the digital-to-analog
converter (DAC) outputs. The dual reconstruction filters
remove high-frequency signals above 6.75MHz. The
Y/C-to-CVBS mixer creates a composite video signal
from luma and chroma. The four amplifiers each have
6dB of gain. The outputs can be DC-coupled to a load of
75Ω, which is equivalent to two video loads, or AC-cou-
pled to a load of 150Ω.
The SmartSleep circuitry intelligently reduces power
consumption based on the presence of the input signal
and the output loads. When the MAX9512 does not
detect the presence of sync on luma, the supply cur-
rent is reduced to less than 7µA. The device only
enables a video amplifier when there is an active video
input signal and an attached load. The video amplifier
remains on while a load is connected. If the load is dis-
connected, the video amplifier is turned off.
The MAX9512 operates from a 2.7V to 3.6V single sup-
ply and is offered in a small, 16-pin TQFN (3mm x
3mm) package. The device is specified over the -40°C
to +125°C automotive temperature range.

Detailed Description
In the Typical Application Circuit (Figure 1), the current
DACs on a video encoder generate luma and chroma
video signals. The MAX9512 filters those signals and
then adds them together to create the composite video
signal. The output amplifiers drive the video connectors
through a 75Ωback termination resistor.
SmartSleep Feature
The SmartSleep feature is activated when the
SMARTSLEEP input is connected to logic high. The
SmartSleep feature provides intelligent power manage-
ment by selectively disabling the filters and output ampli-
fiers based on the presence of a luma video signal or
loads attached to the outputs. If the SmartSleep feature
is not activated and the part is not in shutdown, the filters
and output amplifiers completely turn on, regardless of
whether there is a video signal at the YIN input and
whether there are loads connected at the outputs.
SmartSleep only works with DC-coupled loads.
Standby Mode
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 YIN signal. If no sync is detected
the device remains in standby mode.
