The MAX9541/MAX9542 are quadruple-channel, 2:1
video mux amplifiers with input sync tip clamps. These
devices select between two video sources and support
up to four channels on each source. The MAX9541 has
integrated lowpass filters that are optimized for standard-
definition video signals such as composite and red,
green, blue (RGB). The filters typically have ±1dB pass-
band flatness out to 9.5MHz and 47dB attenuation at
27MHz. The MAX9542 has a wider bandwidth of 15MHz
because it does not have integrated lowpass filters, mak-
ing it suitable for not only standard-definition video sig-
nals, but also video graphics array (VGA) signals with a
640 x 480 resolution at up to 85Hz refresh rate.
Video signals are AC-coupled to the inputs of the
MAX9541/MAX9542. The input sync-tip clamps set the
internal DC level.
The amplifiers have 2V/V gain, and the outputs can be
DC-coupled to a 75Ω load, which is the equivalent of two
video loads, or AC-coupled to a 150Ω load.
Both the MAX9541/MAX9542 feature a low-power shut-
down mode, in which supply current is reduced to 35µA.
