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.
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.
