MAX11505

19-1057; Rev 0; 11/07 Four-Channel, Standard-Definition Video Filter General Description The MAX11504/MAX11505 integrated filters offer four channels of 5th order filters for standard-definition video and include +6dB output buffers on each channel. These video filters are ideal for anti-aliasing and DAC smoothing in applications such as set-top boxes, security systems, digital video recorders (DVRs), DVD players, and personal video recorders. The MAX11504/MAX11505 video inputs feature a transparent clamp compatible with AC- and DC-coupled www.DataSheet4U.com input signals and allow DAC outputs to be directly coupled. The 5 th order filters provide a bandwidth of 8.6MHz (typical). The MAX11504 offers a flat passband response on all channels. The MAX11505 offers a 0.8dB peaking passband response on Channel 1, resulting in a bandwidth of 8.9MHz (typical) and a flat passband response on all other channels. Each channel includes an output buffer with a gain of +6dB capable of driving a full 2VP-P video signal into two standard 150Ω (75Ω back terminated) video loads. The buffers drive either AC- or DC-coupled loads and assure a blanking level below 1V after the back-match resistor. The MAX11504/MAX11505 operate from a single +5V supply and are available in the 0°C to +70°C commercial temperature range. These devices are available in small 10-pin µMAX® packages. ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ Features ♦ Four-Channel 5th Order Filter for StandardDefinition Video +6dB Output Buffers Transpare...
