Description

The FMS6363 low-cost video filter (LCVF) is intended to

replace passive LC filters and drivers with a low-cost

integrated device. Three sixth

-order filters provide

improved image quality compared to typical lower-order

passive solutions.

The FMS6363 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 (see Applications section for details).

The outputs can drive AC-or DC-coupled single (150Ω)

loads. DC-coupling the outputs removes the need for

output coupling capacitors. The input DC levels are offset

approximately +280mV at the output (see Applications

section for details).

Functional Description The FMS6363 Low-Cost Video Filter (LCVF) provides 6dB gain from input to output. In addition, the input is slightly offset to optimize the output driver performance. The offset is held to the minimum required value to decrease the standing DC current into the load. Typical voltage levels are shown in Figure 8. 0.65 V YIN Driver 1.02V YOUT 800kΩ 0.32V 0.02V V IN 0.88V 0.28V Figure 9.

External Video source must be AC-coupled. 75Ω The FMS6363 is specified to operate with output currents typically less than 50mA, more than sufficient for a single (150Ω) video load. Internal amplifiers are current limited to a maximum of 100mA and should withstand brief duration, short-circuit conditions; however, this capability is not guaranteed. Output Considerations 7.5MΩ 0.1µ LCVF Bias Input The FMS6363 outputs will be DC offset from the input by 150mv therefore VOUT = 2*VIN DC+150mv.
PAGE 7
Layout and supply bypassing play major roles in highfrequency performance and thermal characteristics. Minimize all trace lengths to reduce series inductances. If routing across a board, place device such that longer traces are at the inputs rather than the outputs. If using multiple, low-impedance DCcoupled outputs, special layout techniques may be employed to help dissipate heat. If a multilayer board is used, a large ground plane directly under the device helps reduce package case temperature.
