VF8143

DESCRIPTION 

The UTC VF8143 Low-Cost Video Filter (LCVF) offers three

channels of 4th-order filters for standard-definition and drivers with 

a low-cost integrated device. 

The UTC VF8143 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 VF8143 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.
