SGM9131
3-Channel, Video Filter
Driver for HD (1080i)
PRODUCT DESCRIPTION
The SGM9131 video filter is intended to replace passive
LC filters and drivers with an integrated device. Three
6th-order channels offer High Definition (HDi) filters. The
SGM9131 may be directly driven by a DC-coupled DAC
output or an AC-coupled signal. Internal bias circuitry
provides constant bias voltage for AC-coupled inputs.
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
 Bias Mode Active with AC-Coupled Inputs
 Bias Mode Inactive with DC-Coupled Inputs
 AC- or DC-Coupled Outputs
 DC-Coupled Output Eliminates AC Coupling Capacitor
 Available in Green SOIC-8 Package
 -40°C to +85°C Operating Temperature Range
The SGM9131 is available in Green SOIC-8 package. It
operates over an ambient temperature range of -40℃ to
+85℃.
