Hi there!
ATM I'm in the development phase for a new device, which includes the interconnection of a 19" rack with a desktop remote control. I use a I²C connection for data transfer and control, powered by a msp 430 µC, which also provides the clock signal.
Right now, I'm at the point to deliver two stereo and one monosignal from one device to another, and ideally this will also take place in the digital domain, because i want some DSP filters included in the signal chain. So i crawl around the interwebs and i laid eye on the I²S standart. As far as my research goes, the standart only provides a few centimeters of distance.
My goal would be to distribute the signal over a cable about 5-10 meters...for I²C there are some buffers like the PCA9600 (http://www.nxp.com/products/interface-and-connectivity/interface-and-system-management/i2c/i2c-voltage-level-translators/dual-bidirectional-bus-bufferCA9600) available to shift the signal to a higher voltage level, so that the distribution over a long distance is possible. I've talked to another developer, and he managed to succsessfully distribute the I²C signal over 20m with this 'trick'.
My question to you guys would be: are there any similar methods for I²S?
I've found some level buffers which are able to shift the signal level and have enough lanes, like the MAX13030E (https://www.maximintegrated.com/en/products/interface/level-translators/MAX13030E.html), but i'm not sure if there are certain limitations, because there is no explicit IC for this problem available (at least i did't found something)...
Does anyone around here have experience with I²S and could give me some advice?
Thanks in advance!
