MAXIM MAX11506, MAX11507 Technical data

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 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
2V

P-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. DC­coupling 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
