Quadruple, 2:1, Mux Amplifiers For Standard Definition And VGA Signals

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. By Maxim Integrated Products
