VF8146数据手册UTC中文资料规格书

描述 Description

The UTC VF8146 Low-Cost Video Filter (LCVF) offers six channels of 4th-order filters for standard-definition and drivers with a low-cost integrated device. The UTC VF8146 inputs feature a transparent clamp compatible with AC- coupled and DC-coupled input signals 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 approximately +280mV at the output (see Applications section for details). The UTC VF8146 is ideal for DAC smoothing in applications such as cable set-top boxes, satellite set-top boxes, HDTV, video on demand (VOD), DVD players, and personal video recorders.
