SGM9137

SGM9137 4-Channel, Video Filter Driver for SD/HD (1080i) PRODUCT DESCRIPTION The SGM9137 video filter is intended to replace passive LC filters and drivers with an integrated device. One 6th-order channel offers Standard Definition (SD) filter while the other three channels are High Definition (HDi) filters. The SGM9137 may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal clamp and bias circuitry may be used if AC-coupled inputs are required. The outputs can be AC- or DC-coupled. DC coupling the outputs removes the need for large output coupling capacitors. FEATURES  Three 6th-Order Filters for 1080i High Definition Mode  One 6th-Order Standard Definition Filter  Clamp Mode on SD Channel Input  Bias Mode on HD Channel Input  Clamp or Bias Mode Active with AC-Coupled Inputs  Clamp or Bias Mode Inactive with DC-Coupled Inputs  AC- or DC-Coupled Outputs  DC-Coupled Output Eliminates AC Coupling Capacitor  Available in Green TSSOP...
