19-3790; Rev 1; 9/05 Single-Channel Video Reconstruction Filters and Buffers General Description The MAX7462/MAX7463 single-channel, standard-definition, integrated video reconstruction filters and buffers are ideal for anti-aliasing and digital-to-analog smoothing video applications or wherever analog video is reconstructed from digital data (such as cable/satellite/terrestrial set-top boxes and DVRs). The MAX7462 includes a disable function, which places the output in a high-impedance state allowing multiplexing of multiple output signals. It also has an external gain control that sets the output buffer gain to either +6dB or +9.5dB. The higher gain setting allows a lower DAC output signal than the standard 1VP-P signal. The MAX7463 output buffer has a fixed gain of +6dB. The MAX7462/MAX7463 operate from a single +5V supply and have a flat passband out to 5MHz with a stopband attenuation of -43dB (typ) at 27MHz. These devices can drive two standard 150Ω AC-coupled or DC-coupled video loads. The output black level of the MAX7462/MAX7463 is less than 1V for DC-coupled outputs. www.DataSheet4U.com Features ♦ Standard-Definition CVBS Video Reconstruction Filters and Buffers ♦ Passband: -0.05dB at 5MHz ♦ Stopband: -43dB at 27MHz ♦ Selectable Gain: +6dB and +9.5dB (MAX7462) ♦ Output Disable (MAX7462) ♦ Drives 2VP-P into Two 150Ω Video Loads ♦ Output Black Level < 1V for DC-Coupled Output ♦ Very Small µMAX and SO Packages MAX7462/MAX7463 Ordering Information PART MAX7462UUA* MAX7462USA MAX7463USA PINPACKAGE 8 µMAX 8 SO 8 SO BUFFER GAIN (dB) +6/+9.5 selectable +6/+9.5 selectable +6 fixed OUTPUT DISABLE Yes Yes No The MAX7462 is available in an 8-pin µMAX® package and an 8-pin SO package.
