The 34831 is a very high performance triple video reconstruction filter and buffer that can be programmed to process 1080p/1080i/ 720p/ 480p/480i format video signals. Each channel has an integrated input clamp which works with all sync formats and all types of video signals.
The 34831 has four cutoff frequency settings optimized for HDTV, EDTV and SDTV signals. Current consumption reduces with lower frequency settings hence saving power which is critical for portable applications. Each channel has an 8th order lowpass filter which lets the video signal pass through and attenuates DAC clock noise.
Each channel can drive two standard video loads which are DC or AC coupled. Input signal can be DC or AC coupled. 34831 can be disabled with shutdown current being 2.5 mA.
