General Description
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.
