Hey guys I'm hoping someone can point me in the right direction here. My goal is to receive 12 and transmit 4 channels of 24 bit audio @ 48KHz over 100ft to 300ft. I would guess that at this distance I need differential signals. The Cat 5 cable would then have the following twisted pairs
1) Vcc and Gnd
2) Clk + and -
3) Transmit + and -
4) Receive + and -
Given the receive of 12 channels being the limiting case: 12 * 24 * 48000 = 13.824 MHz would appear to be the bandwidth requirement of this situation. The RS-485 spec states that the max bandwidth @ 40ft is only 10 MHz.
I know this sort of thing is possible as I've seen it all the time in digital snakes, etc. Any help would be greatly appreciated!
Thanks!
