... SCART and EVC cables are supported for composite, component, and RGB video. 1V input signals from DACs are AC coupled into the P-P ML6429, where they are DC restored. Outputs are AC coupled, and drive 2V into a 150Ω load. The ML6429 P-P can be used with DC coupled outputs for certain applications ...

... B/Y3 inputs to provide INU necessary sync signals to other channels (R,G,B,Y,C). Otherwise, sync must be provided at SYNCIN. For RGB applications, the green channel with sync can be used as an input to this pin. (see RGB Applications section) 2 ML6429 24-Pin SOIC (S24) A/B MUX INF / INU A/Y2 ...

... FUNCTIONAL DESCRIPTION The ML6429 is a quad monolithic continuous time analog video filter designed for reconstructing signals from four video D/A sources. The ML6429 is intended for use in AC coupled input and output applications. th The filters approximate a 4 -order Butterworth characteristic with an optimization toward low overshoot and flat group delay ...

... B channel can be used as a chroma input. Composite outputs and an H-sync output is also provided. There are several configurations available with the ML6429. Figure 4 includes a list of basic output options for composite, S-video, TV modulator, and RGB outputs. Note that each composite channel can drive a CV load or a channel modulator simultaneously ...
