1. Introduction
function: input one channel of HDMI signal, and can output 4 channels of the same HDMI signal at the same time. Applications: HDMI split screen, HDMI audio splitter, video conferencing, multimedia teaching, shopping mall display, large screen monitoring, set-top box distribution, etc. Principle: Use MS9334 for HDMI 1 in and 4 out, and MS8005 for IIC control. 2. Purchase MS9334+MS8005
MS9334 is controlled by IIC, but I searched all over the Internet and couldn't get the register manual of MS9334. It is the same as the previous MS9332, but Ma Yun sells ICs matching MS8005 online, so you can use ready-made ICs without programming.
