  • Descriptioin

The CN3311 low voltage, single channel 6th order SD video filter is intended to replace passive LC filter and drivers with a low-cost integrated device. The CN3311 can 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 output can drive AC or DC coupled single (150Ω) or dual (75Ω) loads. DC coupling the outputs removes the need for output coupling capacitors.
