General Description

The MAX7469/MAX7470 triple-channel, anti-aliasing fil-

ters and buffers are ideal for high-definition (HD) and

standard-definition (SD) television (TV) applications.

Compatible with 1080i, 720p, 720i, 480p, and 480i

scanning system standards and computer format sig-

nals, the MAX7469/MAX7470 support component video

(Y P

, G

BR, and RGBHV), as well as composite

(CVBS) and S-video (Y/C).

The MAX7469/MAX7470 limit the input bandwidth for

anti-aliasing and out-of-band noise reduction prior to

digital conversion by an ADC or video decoder. The

MAX7469/MAX7470 frequency response can be contin-

uously varied in 256 linear steps through an I

C* inter-

face from below SD resolution to beyond HD resolution.

The output buffers of the MAX7469/MAX7470 drive a

P-P

video signal into a standard 150Ω load. The inputs

are AC-coupled, and the outputs can be either DC- or

AC-coupled. The MAX7469 has a gain of 0dB, and the

MAX7470 has a gain of +6dB. Both devices are available

in a 20-pin TQFN package and are fully specified over

the 0°C to +85°C upper-commercial temperature range.
