3.3V, HD/SD Triple-Channel Filter Amplifiers
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.

Figure 2. Triple DAC is connected to both a SCART device and a high-definition, video-filter amplifier. (A) SCART device is transmit-
ting standard-definition RGB signals while the HD filter amplifier is in shutdown mode; (B) SCART device is not transmitting RGB sig-
nals, but the HD filter amplifier device is transmitting high-definition YPbPr signals.
