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.
The MAX11506 and MAX11507 integrated filters provide six channels—three for standard‑definition (SD) video and three that can be switched between SD and high‑definition (HD) video. Each channel includes a transparent input clamp, a low‑pass filter (9 MHz for SD, 33 MHz for HD) and a +6 dB output buffer capable of driving a 150 Ω video load.
These devices operate from a single +5 V supply, are available in a lead‑free 16‑pin QSOP package, and are rated for commercial temperature ranges from 0 °C to +70 °C. They are suited for set‑top boxes, DVD players, digital video recorders and other video‑processing applications.
