Three-Channel, High-Definition Video Filter
General Description
The MAX11500 integrated three-channel high-definition
(HD) video filter includes input video clamps and output
buffers. This device is ideal for anti-aliasing and DAC
smoothing video applications such as set-top boxes,
hard-disk recorders (HDRs), DVD players, and person-
al video recorders.
The 6th-order channel filters have a typical -3dB band-
width of 33MHz. Each channel has an output buffer with
a gain of +6dB and can drive a full 2V_P-P video signal
into one standard 150Ω video load. These buffers can
drive either an AC- or DC-coupled load such that the
blanking level voltage after the backmatch resistor is
less than 1V.
The video inputs feature a transparent clamp for AC-
and DC-coupled input signals. If the input signal does
not go below ground, the input clamp is inactive, thus
enabling DAC outputs to be DC-coupled to the input.
The device operates from a single +5V supply, is offered
in the upper commercial 0°C to +85°C temperature
range, and is available in a small 8-pin SO package.
