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-coupled to a load of 150Ω.
