The FMS6143A VoltagePlus™ video filter is intended to replace passive LC filters and drivers with a cost-effective integrated device. Three 6th-order filters provide improved image quality compared to typical 2nd- and 3rd-order passive solutions.The FMS6143A may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required.The outputs can drive AC- or DC-coupled single (150 Ω) or dual (75 Ω) video loads. DC coupling the outputs removes the need for large output coupling capacitors. The input DC levels are offset approximately +280 mV at the output.

The FMS6151 low-cost integrated video filter is intended to replace passive LC filters and drivers in low-voltage portable video applications. The 5th-order filter provides better image quality compared to typical 2nd- and 3rd-order passive solutions.The FMS6151 is intended to be directly driven by a DC-coupled DAC output. The output can drive an AC- or DC-coupled doubly terminated coax (150 Ω) load. DC-coupling the output removes the need for an expensive output coupling capacitor. If an AC-coupled output is needed, the SAG correction circuit can be used to reduce the AC output coupling capacitor value. Input DC levels are offset by approximately 100 mV. This internal level shift is incorporated to prevent sync pulse clipping.Offering SAG correction, 6 dB fixed gain, and a 5th-order low-pass filter in a space-saving MicroPak™ package makes the FMS6151 well suited for space-sensitive applications, such as cellular phones and digital cameras.

The FMS6203 offers comprehensive filtering for set top-box or DVD applications. It is intended to replace passive LC filters and drivers with a low-cost integrated device.Filter channels are specialized for either component (YPbPr) or RGB video signals. These channels offer a selectable frequency response of 8, 16, or 32MHz. The filters can also be bypassed for high-frequency operation. Additional functionality of these channels include input biasing mode and output disable. The FMS6203 may be driven directly by a DC-coupled DAC output or an AC-coupled signal. All inputs accept standard 1VPPvideo signals. Each channel includes an output amplifier capable of driving a single (150Ω), AC or DC-coupled video load. All outputs can be disabled to save power in DC coupled applications.The device is available in two factory set options, a 0dB gain option and a 6dB gain option.

The FMS6404 is a single composite video 5th-order Butterworth low-pass video filter optimized for minimum overshoot and flat group delay. The device contains an audio trap that removes video information in a spectral location of the subsequent RF audio carrier. The group delay compensation circuit pre-distorts the signal to compensate for the inherent receiver intermediate frequency (IF) filter’s group delay distortion.In a typical application, the composite video from the DAC is AC coupled into the filter. The CV input has DC-restore circuitry to clamp the DC input levels during video synchronization. The clamp pulse is derived from the CV channel.All outputs are capable of driving 2VPP, AC- or DC-coupled, into either a single or dual video load. A single video load consists of a series 75 Ω impedance matching resistor connected to a terminated 75 Ω line. This presents a total of 150 Ω of loading to the part. A dual load would be two of these in parallel, which presents a total of 75 Ω to the part. The gain of the CV signal is 6dB with 1 VPPinput levels. All video channels are clamped during synchronization to establish the appropriate output voltage reference levels.
