FMS6363A Three-Channel 7th-Order High-Definition VoltagePlus™ Video Filter Driver
Features
Three 7th-Order 32MHz (HD) Filters Drives Single AC-or DC-Coupled Video Loads (150Ω) Drives Dual AC-or DC-Coupled Video Loads (75Ω) Transparent Input Clamping Single Supply: 3.3V – 5V AC-or DC-Coupled Inputs and Outputs DC-Coupled Output Eliminates AC-Coupling Capacitor Robust 9kV ESD Protection Lead-Free SOIC-8 Package
Description
The FMS6363A VoltagePlus™ video filter is intended to replace passive LC filters and drivers w ith a costth effective integrated device. T he three 7 -order filters provide improved frequency response performance over the FMS6363 and other 3-channel HD VFD devices. The FMS6363A 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) or dual (75 Ω) video loads. DC coupling the outputs removes the need for large out put coupling capacitors. The input DC levels are offset approximately +280mV at the output (see Applications section for details).
