Low-Cost, 3-Channel, SD Video Filter Drivers with External Delay Control
Features
■ Three Fourth-Order 8MHz (SD) Filters ■ External Delay Control ■ Transparent Input Clamping ■ Dual-Video Load Drive (2Vpp, 75Ω) ■ AC- or DC-Coupled Inputs ■ AC- or DC-Coupled Outputs ■ DC-Coupled Outputs Eliminate AC-Coupling
Description
The FMS6243 Low-Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a low-cost integrated device. Three fourth-order filters provide improved image quality compared to typical second- or third-order passive solutions. The FMS6243 can be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal diode clamps and bias circuitry can be used if AC-coupled inputs are required (see the Applications section for details). Delay for each channel can be independently controlled with an external capacitor. The outputs can drive AC- or DC-coupled single (150Ω) or dual (75Ω) loads. DC coupling the outputs removes the need for output coupling capacitors. The input DC levels are offset approximately +280mV at the output www.DataSheet4U.com (see the Applications section for details).
