MAX9501

19-3779; Rev 1; 11/05 Triple-Channel HDTV Filters General Description www.datasheet4u.com Features ♦ 30MHz Bandwidth at ±1.5dB ♦ Extremely Sharp Rolloff, Lowpass Filters -50dB at 44.25MHz ♦ DC-Coupled Inputs; AC- or DC-Coupled Outputs ♦ ±5V Dual Supply (MAX9501) ♦ 5V Single Supply (MAX9500) ♦ Matched Group Delay and Gain ♦ Drive Single/Double Back-Terminated Loads (150Ω/75Ω) Directly to Ground ♦ Sink and Source Output Current ♦ High Input Impedance to Interface to Low OutputCurrent DAC ♦ 16-Pin SO and QSOP Packages MAX9500/MAX9501 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 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 75Ω back-terminated loads to unity gain. The DC-coupled input eli...
