General Description
The FMS6414 Dual Channel Video Filter
- Driver Chip offers prehensive video filtering for set top box or DVD applications. This part consists of two 4th order video Low Pass Filters for video filtering. This device integrates video drivers so that it can directly drive to the outside world. The video signals are filtered at 7.1MHz and buffered to drive 2Vp-p into AC coupled 150Ω loads with up to 35p F of load capacitance at the output pin. The filters approximate a 4th-order Butterworth characteristic with an optimization toward low overshoot and flat group delay. Likewise, they are capable of driving a 75Ω load at 1Vp-p. There is an option for the video output...
