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. The outputs are AC coupled. The Y, C and, CV outputs are buffered to drive 2VP-P into a 150 Ω load (1VP-P into a doubly terminated 75 Ω coax load) with up to 35pF of load capacitance at the output pin. The Y, C, and CV channels have a gain of approximately 2 (6dB) with 1VP-P input levels. There is an option for the video output to be DC coupled which limits the drive output to one output on each channel.
