The MAX11506/MAX11507 integrated filters offer six channels, three for standard-definition (SD) video and three for either SD or high-definition (HD) 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, digital video recorders, DVD players, and personal video recorders.
The MAX11506/MAX11507 video inputs feature a transparent clamp compatible with AC- and DC-coupled input signals and allow DAC outputs to be directly coupled. The filters provide -3dB bandwidth of 9.0MHz for the SD filters and 33MHz for the HD filters. Each channel includes an output buffer with a gain of +6dB capable of driving a full 2VP-P video signal into a 150Ω video load. The buffers drive either AC- or DC-coupled loads and assure a blanking level of below 1V after the backmatch resistor. DC-coupling eliminates bulky coupling capacitors.
The MAX11506 offers a flat passband while the MAX11507 features 0.8dB peaking on the three SD-only channels to compensate for system roll-off. The MAX11506/MAX11507 operate from a single +5V supply and are available in the 0°C to +70°C commercial temperature grade. The MAX11506/MAX11507 are offered in the 16-pin QSOP package.
