Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe 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 currentoutput,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 75 back-terminated loads to unity gain.The DC-coupled input of MAX9500 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/SMPTE274M 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 16-pin SO and compact 16-pin QSOP packages, and are fully specified over the -40°C to +85°C extended temperature range.
