GENERAL DEscriptION
The SGM9146 is a 4-channel, 6th-order output reconstruction filter which can operate from 3.1V to 5.5V single power supply. It is designed to replace passive LC filters and drivers with an integrated device. One channel is Standard Definition (SD) filter while the rest three channels are configurable between HDi and HDp filters.
The device allows DC- or AC-coupled output. SGM9146 can be DC-coupled or AC-coupled with input video signal to eliminate out-of-band noise, such as the output stage of DAC. Internal clamp and bias circuitry may be used if AC-coupled inputs are required.
The SGM9146 is available in a Green TSSOP-14 package. It operates over an ambient temperature range of -40℃ to +85℃.
