Both AG7130 and AG7231 are used to design HDMI KVM switch solutions and HDMI KVM controller solutions. The specific application methods are as follows:
One set of keyboard and mouse, one monitor, you can control the two hosts to switch freely
Two hosts can share printers, U disks and other equipment, saving you office costs
The application scenarios of AG7130 and AG7231 are described as follows:
In terms of specific options, how to correctly correspond to various parameters and characteristics in the following table:
AG7130 and AG7231 are both used in two-in-one design, which is to switch the signal between two HDMI hosts to a set of USB keyboard/mouse and an HDMI display. AG7130 can be used as HDMI1.4 2:1 KVM (keyboard-video- Mouse) switch controller, AG7231 can be used as HDMI2.0 2:1 KVM (keyboard-video-mouse) switch controller, HDMI1.4 is mainly used for HDMI signal 4K 30Hz products, HDMI2.0 is mainly used In the HDMI signal of 4K 60Hz products, the specific switching method between AG7130 and AG7231 is shown in the figure below:
