Three-Channel,
Standard-Definition Video Filters
General Description
The MAX11501/MAX11502 integrated filters offer three
channels of 5th-order filters for standard-definition
video and include +6dB output buffers on each chan-
nel. These video filters are ideal for anti-aliasing and
DAC smoothing in applications such as set-top boxes,
security systems, digital video recorders (DVRs), DVD
players, and personal video recorders.
The MAX11501/MAX11502 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 5th-order filters provide a typical -3dB band-
width of 8.6MHz (MAX11501) and 8.9MHz (MAX11502)
and offer either a flat passband response (MAX11501)
or a +0.8dB peaking passband response (MAX11502)
on all 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 of below 1V after the back-
match resistor.
The MAX11501/MAX11502 operate from a single +5V
supply and are available in the upper commercial 0°C
to +85°C temperature range. These devices are avail-
able in small 8-pin SO packages.
