FMS6413
Single Channel Video Driver with Integrated Filter and Clamp
Video Features
Integrated Video Low Pass reconstruction filter Integrated output driver provides a low impedance output and delivers 2Vp-p (6dB gain) composite video into 150. 7.1MHz 4th order video filter 0.4% differential gain with 0.4 differential phase Integrated DC Restore / Clamp Circuitry

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 4th 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 150 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 75 load at 1Vp-p. There is an option for the video output to be DC coupled which limits the drive to 1 output.

Applications
CCTV DVD players Televisions HDTV Personal Video Recorders (PVRs) Video On Demand (VOD) Cable and Satellite Set top boxes
