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

Functional Description
Introduction
The FMS6413 is a monolithic continuous time video filter driver designed for reconstructing the video signals from a D/A source. This chip is intended for use in applications with AC coupled input and AC coupled outputs. (See Figure 1) The reconstruction filter approximates a 4th-order Butterworth characteristic with an optimization toward low over-shoot and flat group delay. The video output is capable of driving 2VP-P into an AC coupled 150 video load, with up to 35pF of load capacitance at the output pin. The channel is clamped during sync to establish the appropriate output voltage swing range. Thus the input coupling capacitor does not behave according to the conventional RC time constant. Clamping for the video channel settles to less than 10mv within 5ms of a change in video input source. In most applications the input coupling capacitor is 0.1F. The input typically sinks 1A during active video, which nominally tilts a horizontal line by about 2mV at the Video output. During sync, the clamp typically sources 20A to restore the DC level. The net result is that the average input current is zero. Any change in the input coupling capacitor's value will inversely alter the amount of tilt per line. Such a change will also linearly affect the clamp response time. This product is robust and stable under all stated load and input conditions. Capacitive bypassing VCC directly to ground ensures this performance.
Video I/O
The video input is driven by either a low impedance source of 1VP-P or the output of a 75 terminated line. The input is required to be AC coupled via a 0.1F coupling capacitor which allows for a settling time of 5ms. The video output is capable of driving an AC coupled 150 load at 2VP-P, or 1VP-P into a 75 load. Up to 35pF of load capacitance (at the output pin) can be driven without stability or slew issues. The output is AC coupled with a 220F or larger AC coupling capacitor.
