Max9513 Cvbs Video Filter Amplifier With Smartsleep And Bidirectional Video Support
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
1.MAX9513ATET.pdf (23 pages)
The MAX9513 CVBS video filter amplifier with
SmartSleep and bidirectional video support is ideal for
portable DVD players and portable media players
(PMPs). The input can be directly connected to the digi-
tal-to-analog converter (DAC) output. 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 75Ω, which is equivalent to two
video loads, or can be AC-coupled 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 MAX9513 does not
detect the presence of sync on the input video signal,
the supply current 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 disconnected, the video amplifier is turned off.
The MAX9513 contains one reconstruction filter, two
video amplifiers, and a pulldown switch at one of the
two CVBS outputs. The MAX9513 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 MAX9513 operates from a 2.7V to 3.6V single supply
and is offered in small 16-pin TQFN (3mm x 3mm) and
16-pin QSOP packages. The device is specified over
the -40°C to +125°C automotive temperature range.
