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 trans-
parent clamp compatible with AC- and DC-coupled
input signals and allow DAC outputs to be directly cou-
pled, eliminating the need for bulky coupling capaci-
tors. The filter bandwidths are selectable to HD, PS,
and SD. A BP mode is provided for 1080p and high-
bandwidth 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
load. The buffers drive either AC- or DC-coupled loads
and assure a blanking level of below 1V after the back-
match 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 commer-
cial (0°C to +85°C) temperature range. The parts are
offered in the 14-pin TSSOP package.
