FMS6243

Low-Cost, 3-Channel, SD Video Filter Drivers with

External Delay Control

Features

Description

■ Three Fourth-Order 8MHz (SD) Filters

■ External Delay Control

The FMS6243 Low-Cost Video Filter (LCVF) is intended

to replace passive LC filters and drivers with a low-cost

integrated device. Three fourth-order filters provide

improved image quality compared to typical second- or

third-order passive solutions.

■ Transparent Input Clamping

■ Dual-Video Load Drive (2Vpp, 75Ω)

■ AC- or DC-Coupled Inputs

■ AC- or DC-Coupled Outputs

■ DC-Coupled Outputs Eliminate AC-Coupling

Capacitors

The FMS6243 can be directly driven by a DC-coupled

DAC output or an AC-coupled signal. Internal diode

clamps and bias circuitry can be used if AC-coupled

inputs are required (see the Applications section for

details).

■ 5V Only

■ Lead-Free Package: TSSOP-14

Delay for each channel can be independently controlled

with an external capacitor.

Applications

■ Cable Set-Top Boxes

■ Satellite Set-Top Boxes

■ DVD Players

The outputs can drive AC- or DC-coupled single (150Ω)

or dual (75Ω) loads. DC coupling the outputs removes

the need for output coupling capacitors. The input DC

levels are offset approximately +280mV at the output

(see the Applications section for details).

■ HDTV

■ Personal Video Recorders (PVR)

■ Video On Demand (VOD)
