SGM9146 4-Channel, Video Filter Driver for SD/HD (1080i)/HD (1080p)

GENERAL DESCRIPTION

The SGM9146 video filter is intended to replace passive LC filters and drivers with an integrated device. One 6th-order channel offers SD filter while the other three HD filters are configurable between HDi and HDp filters. The SGM9146 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.

The SGM9146 is available in Green TSSOP-14 package. It operates over an ambient temperature range of -40 to +85.
