MAX7462/MAX7463 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 lower DAC output signal than the standard 1VP-Psig-nal. The MAX7463 output buffer has a fixed gain of+6dB.
◆The MAX7462/MAX7463 operate from a single +5Vsupply and have a flat passband out to 5MHz with a stopband attenuation of -43dB (typ) at 27MHz.
◆These devices can drive two standard 150ΩAC-coupled or DC-coupled video loads. The output black level of the MAX7462/MAX7463 is less than 1V for DC-coupled outputs.
◆The MAX7462 is available in an 8-pin μMAX®package and an 8-pin SO package. The MAX7463 is available in an 8-pin SO package. All devices are specified over the 0°C to +85°C temperature range.
