ML6429

ML6429 75Ω Quad Video Cable Drivers and Filters with Switchable Inputs GENERAL DESCRIPTION The ML6429 is a quad 4th-order Butterworth lowpass reconstruction filter plus quad video amplifier optimized for minimum overshoot and flat group delay. Each filter channel has a two-input multiplexer that switches between two groups of quad video signals. Applications driving SCART and EVC cables are supported for composite, component, and RGB video. 1VP-P input signals from DACs are AC coupled into the ML6429, where they are DC restored. Outputs are AC coupled, and drive 2VP-P into a 150Ω load. The ML6429 can be used with DC coupled outputs for certain applications. A fifth unfiltered channel is provided to support an additional analog composite video input. A swapping multiplexer between the two composite channels allows the distribution amplifiers to output from either input. Several ML6429s can be arranged in a master-slave configuration where an external sync can be used for CV and RGB outputs.
