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

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.
