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.
