This part consists of two 4th order Butterworth 7.1MHz low pass filters for video signals. The filters are optimized for low overshoot and flat group delay. The device also contains a summing circuit to generate filtered composite video. Integrated video drivers are included to facilitate a direct drive to the outside world. In a typical application, the Y and C input signals from DACs are AC coupled into the filter. Both channels have DC restore circuitry to clamp the DC input levels during video sync. The Y and C channels use a separate feedback clamp. The clamp pulse is derived from the Y channel...
