The MAX7469/MAX7470 triple-channel, anti-aliasing filters and buffers are ideal for high-definition (HD) and standard-definition (SD) television (TV) applications. Compatible with 1080i, 720p, 480p, and 480i scanning system standards and computer format signals, the MAX7469/MAX7470 support component video (Y Pb Pr, GsBR, 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 continuously varied in 256 linear steps through an I²C interface from below SD resolution to beyond HD resolution. The output buffers of the MAX7469/MAX7470 drive a 2VP-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.
