with Shutdown
General Description
The MAX9652/MAX9653/MAX9654 are 3.3V, triple-
channel, 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 sync-
tip clamp while PBIN and PRIN have keyed clamps.
The output buffer has gain of 2V/V and drives a stan-
dard 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.
The devices consume only 9.5mA per channel and
operate from a 3.3V supply. The MAX9653/MAX9654
feature a low-power, 12µA shutdown mode. The
MAX9652/MAX9653/MAX9654 are specified over the
-40°C to +125°C automotive temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
