General Description
The FMS6413 Single Channel Video Filter – Driver Chip
offers comprehensive video filtering for set top box or DVD
applications. This part consists of a 4^th order video Low
Pass filter for video filtering. This device integrates a video
driver so that it can directly drive to the outside world. There
is also an integrated clamp circuit that allows the part to DC
restore.
The video output is filtered at 7.1MHz and buffered to drive
2Vp-p into an AC coupled 150Ω load with up to 35pF of
load capacitance at the output pin. The filter approximates a
4th-order Butterworth characteristic with an optimization
toward low overshoot and flat group delay. Likewise, the
driver is capable of driving a 75Ω load at 1Vp-p. There is an
option for the video output to be DC coupled which limits
the drive to 1 output.
