MAXIM MAX11508, MAX11509 Technical data

General Description

The MAX11508/MAX11509 integrated 3-channel video
filters for high-definition (HD), progressive-scan (PS),
standard-definition (SD), and bypass (BP) video
include an output buffer with +6dB gain and are ideal
for digital video disc (DVD) players, set-top box (STB)
receivers, high-definition television (HDTV), digital
video recorders (DVRs), and similar devices.

The MAX11508/MAX11509 video inputs feature a trans­parent clamp compatible with AC- and DC-coupled
input signals and allow DAC outputs to be directly cou­pled, eliminating the need for bulky coupling capaci­tors. The filter bandwidths are selectable to HD, PS,
and SD. A BP mode is provided for 1080p and high­bandwidth RGB signals. Selectable input bias circuitry
on 2 filter channels offers simple connection to bipolar
video signals such as C, Pb, and Pr.

The MAX11508 filters provide -3dB bandwidths of 9MHz
(SD), 16MHz (PS), 33MHz (HD), and 60MHz (BP). The
MAX11509 filters provide -3dB bandwidths of 10MHz
(SD), 17MHz (PS), 34MHz (HD), and 60MHz (BP).

Each channel includes an output buffer with +6dB gain
that provides 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. The shutdown mode provided reduces
device current to 1µA (typ).

The MAX11508 offers a flat passband and the
MAX11509 features +0.8dB peaking to compensate for
DAC rolloff. The MAX11508/MAX11509 operate from a
5V power supply and operate over the upper commer­cial (0°C to +85°C) temperature range. The parts are
offered in the 14-pin TSSOP 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.
