Four-Channel, Standard-Definition
Video Filter
General Description
The MAX11504/MAX11505 integrated filters offer four
channels of 5^th order filters for standard-definition video
and include +6dB output buffers on each channel. These
video filters are ideal for anti-aliasing and DAC smooth-
ing in applications such as set-top boxes, security sys-
tems, digital video recorders (DVRs), DVD players, and
personal video recorders.
The MAX11504/MAX11505 video inputs feature a trans-
parent clamp compatible with AC- and DC-coupled
input signals and allow DAC outputs to be directly cou-
pled. The 5^th order filters provide a bandwidth of
8.6MHz (typical). The MAX11504 offers a flat passband
response on all channels. The MAX11505 offers a 0.8dB
peaking passband response on Channel 1, resulting in
a bandwidth of 8.9MHz (typical) and a flat passband
response on all other channels.
Each channel includes an output buffer with a gain of
+6dB capable of driving a full 2V_P-P video signal into two
standard 150Ω (75Ω back terminated) video loads. The
buffers drive either AC- or DC-coupled loads and assure
a blanking level below 1V after the back-match resistor.
The MAX11504/MAX11505 operate from a single +5V
supply and are available in the 0°C to +70°C commer-
cial temperature range. These devices are available in
small 10-pin µMAX^® packages.
