ML6426 High Bandwidth Triple Video Filters with Buffered Outputs for RGB or YUV GENERAL DESCRIPTION The ML6426 are a family of triple video filters with buffered outputs. There are several versions of the ML6426, each with different passband cut-off frequencies of 6.7MHz, 12MHz, 15MHz, 24MHz, 30MHz, 36MHz, and 48MHz. Each channel contains a 4th-order Butterworth lowpass reconstruction video filter. The filter is optimized for minimum overshoot and flat group delay and guaranteed differential gain and phase at the outputs of the integrated cable drivers. All input signals from DACs are AC coupled into the ML6426. All channels have DC restore circuitry to clamp the DC input levels during video H-sync, using an output feedback clamp. An external H-sync signal is required for this purpose.
