UNISONIC TECHNOLOGIES CO., LTD VF8143 Preliminary CMOS IC LOW-COST Three-Channel 4TH-ORDER STANDARDDEFINITION VIDEO FILTERS  DESCRIPTION The UT C VF814 3 L ow-Cost Video Filter (LCVF) offer s six channels of 4th-order filters for standard-definition and drivers with a low-cost integrated device. The U TC VF 8143 in puts feature a transparent clamp compatible with AC- couple d and DC-cou pled inp ut sign als and allows DAC outputs to be directly coupled. The outputs can drive AC- or DC-coupled single (150Ω) or dual (75Ω) loads. The input DC levels are offset appr oximately +280mV at the output (see Applications section for details).
