GENERAL DESCRIPTION

The ADA4410-6 is a comprehensive integrated filtering solution

that is carefully designed to give designers the flexibility to

easily filter and drive many types of video signals, including

high definition video. In the GBR/component channels, the

cutoff frequencies of the sixth-order filters can be selected by

two logic pins to obtain four filter combinations that are tuned

for GBR, high definition, and standard definition video. Cutoff

frequencies range from 36 MHz to 9 MHz.

The ADA4410-6 also provides filtering for the legacy standard

S-video and composite video signals. With a differential gain of

0.11% and a differential phase of 0.25°, the ADA4410-6 is an

excellent choice for any composite video (CV) application.

The ADA441-6 offers gain and output offset voltage

adjustments. The gain of the part can be ×2 or ×4, and the

output offset voltage is continuously adjustable up to ±2 V

by applying a differential voltage to an independent offset

control input.

The ADA4410-6 offers 2:1 multiplexers on its inputs that can be

used in applications where multiple sources of video exist.

HD INPUT SELECT

The ADA4410-6 can operate on a single +5 V supply as well as

±5 V supplies. Single-supply operation is ideal for applications

where power consumption is critical. A disable feature allows

for further power conservation.

Dual-supply operation is for applications where the negative-

going excursions of the signal must swing at or below ground

while maintaining excellent video performance. The output

buffers have the ability to drive two 75 Ω terminated loads that

are either dc- or ac-coupled.

The ADA4410-6 is available in a 32-lead LFCSP and operates in

the commercial temperature range of −40°C to +85°C.
