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-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 MAX9512 does not detect the presence of sync on luma, 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 MAX9512 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.
