MAX9500/MAX9501 19-3779 Rev 4 1/07 Triple-Channel HDTV Filters General Description Features The MAX9500/MAX9501 are fully integrated solutions 30MHz Bandwidth at 1.5dB for filtering and buffering HDTV signals. The MAX9500 Extremely Sharp Rolloff, Lowpass Filters operates from a single +5V supply, while the MAX9501 -50dB at 44.25MHz operates from dual 5V supplies. The MAX9500/ DC-Coupled Inputs AC- or DC-Coupled Outputs MAX9501 triple-channel video reconstruction filters are both gain and delay matched and are ideal for use in 5V Dual Supply (MAX9501) set-top boxes, DVD players, and other equipment that 5V Single Supply (MAX9500) generate analog HDTV outputs. Matched Group Delay and Gain The MAX9500/MAX9501 interface between the current- Drive Single/Double Back-Terminated Loads output, digital-to-analog converters (DAC) of an (150 /75 ) Directly to Ground Advanced Television Standard Committee (ATSC), Motion Picture Experts Group (MPEG) decoder and the Sink and Source Output Current external connections of a television, set-top box, or High Input Impedance to Interface to Low Output- DVD player. Current DAC The MAX9500/MAX9501 feature a DC-coupled input with 16-Pin QSOP Package very low input capacitance and high resistance. The highly selective lowpass filters remove spectral replicas Ordering Information at the output of the DAC. The output amplifier has +6dB of gain to drive 75 back-terminated loads to unity gain.
