The MAX9652/MAX9653/MAX9654 are 3.3V, triplechannel,
high-definition (HD) video-filter amplifiers.
Specially designed for YPbPr component video signals,
these devices are ideal for a wide range of set-top box
and portable applications. The inputs to the MAX9652/
MAX9653/MAX9654 are AC-coupled. YIN has a synctip
clamp while PBIN and PRIN have keyed clamps.
The output buffer has gain of 2V/V and drives a standard
back-terminated 75Ω video load.
The passband of the MAX9654 is logic selectable
between standard definition (SD) and high definition. The
MAX9652/MAX9653 have a fixed passband for HD video.
The MAX9654 SD lowpass filter has ±1dB passband out
to 8.5MHz and 57dB attenuation at 27MHz. The
MAX9652/MAX9653/MAX9654 HD lowpass filter have
±1dB passband out to 42MHz and 50dB attenuation at
109MHz.
