LOW-COST Three-Channel

4TH-ORDER STANDARD-

DEFINITION VIDEO FILTERS



DESCRIPTION

The UTC VF8143 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 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.
