General Description
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 smooth-
ing in applications such as set-top boxes, digital video
recorders, DVD players, and personal video recorders.
The MAX11506/MAX11507 video inputs feature a trans-
parent 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 150 video load. The buffers
drive either AC- or DC-coupled loads and assure a blank-
ing 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 tem-
perature grade. The MAX11506/MAX11507 are offered in
the 16-pin QSOP package.
