MAX11500 19-3212; Rev 0; 1/08 EVAALVUAAILTAIOBNLEKIT 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 personal video recorders. The 6th-order channel filters have a typical -3dB bandwidth of 33MHz. Each channel has an output buffer with a gain of +6dB and can drive a full 2VP-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 ACand 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...
