No Preview Available ! 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 smooth- ing in applications such as set-top boxes, security sys- tems, digital video recorders (DVRs), DVD players, and personal video recorders. The MAX11504/MAX11505 video inputs feature a trans- parent clamp compatible with AC- and DC-coupled www.DiantpauStheseigtn4Ua.lcsoamnd allow DAC outputs to be directly cou- pled. The 5th 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 commer- cial temperature range. These devices are available in small 10-pin µMAX® packages.

Ground Video Output Channel 4 Video Output Channel 3 Video Output Channel 2 Video Output Channel 1. The MAX11505 provides 0.8dB passband boost at high frequency. Detailed Description Each channel of the MAX11504/MAX11505 contains a transparent input clamp, a 5th order lowpass filter, and an output amplifier with +6dB gain (see the Functional Diagrams and Typical Operating Circuits). The 5th order lowpass filters provide a bandwidth of 8.6MHz (typical). The MAX11504 provides a flat passband response. The MAX11505 features a 0.8dB high-frequency boost on Channel 1 to help with system rolloff (for CVBS signals) and a flat passband response on all other channels. Within the passband, each channel amplifies the signal by two and adds 280mV of offset.
