General Description

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 75

Ω, which is equivalent to two

video loads, or 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 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 a small 16-pin TQFN (3mm x 3mm)

package. The device is specified over the -40°C to

+125°C automotive temperature range.
