The MAX9500/MAX9501 are fully integrated solutions for filtering and buffering HDTV signals. The MAX9500 operates from a single +5V supply, while the MAX9501 operates from dual ±5V supplies. The MAX9500/MAX9501 triple-channel video reconstruction filters are both gain and delay matched and are ideal for use in set-top boxes, DVD players, and other equipment that generate analog HDTV outputs. The MAX9500/MAX9501 interface between the current-output, digital-to-analog converters (DAC) of an Advanced Television Standard Committee (ATSC), Motion Picture Experts Group (MPEG) decoder and the external connections of a television, set-top box, or DVD player. The MAX9500/MAX9501 feature a DC-coupled input with very low input capacitance and high resistance. The highly selective lowpass filters remove spectral replicas at the output of the DAC. The output amplifier has +6dB of gain to drive 75Ω back-terminated loads to unity gain. The DC-coupled input eliminates problems such as sync crush, droop, and field tilt. The output load can be DC- or AC-coupled, depending on the application. All three channels in the MAX9500/MAX9501 have the same frequency response with matched group delay and gain. The MAX9500/MAX9501 filter response meets the requirements of the EIA-770.3/SMPTE 274M filter template achieving > 40dB attenuation at 44.25MHz. The MAX9500/MAX9501 can also be used as an antialiasing filter for HDTV component inputs. The MAX9500/MAX9501 are available in compact 16-pin QSOP packages and are fully specified over the -40°C to +85°C extended temperature range.
