General Description
The MAX9508 video filter amplifier with SmartSleep and
bidirectional video support is ideal for set-top boxes
(STBs), portable DVD players, and portable media
players (PMPs). The inputs can be directly connected
to the digital-to-analog converter (DAC) outputs. The
reconstruction filter removes high-frequency signals
above 6.75MHz. The amplifiers have 6dB of gain, and
the outputs can be DC-coupled to a load of 75
Ω,
which is equivalent to two video loads, or it can be
AC-coupled to a load of 150
Ω.
The SmartSleep circuitry intelligently reduces power
consumption based on the presence of the input signal
and the output loads. When the MAX9508 does not
detect the presence of sync on the input video signal,
the supply current is reduced to less than 7A. 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 disconnected, the video amplifier is turned off.
The MAX9508 contains three reconstruction filters, four
video amplifiers, and a pulldown switch at one of the
two CVBS outputs. The MAX9508 has the ability to con-
trol the bidirectional video signals at the CVBS video
connections without the need for separate switches or
relays. This feature is particularly useful for portable
DVD players, which often use the same connector to
drive a composite video output and to accept an exter-
nal video signal to display on the LCD panel.
The MAX9508 operates from a 2.7V to 3.6V single supply
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.
