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