All,
Has anyone encountered problems with EMI/noise issues on I2C wires and/or
busses? We use industry standard I2C to interface with our bulk 208V/48V
AC/DC power supplies. We are observing instances where control and status
signals (connected via I2C) for the AC/DC power supplies appear to be
intermittently
in the wrong state. I believe that we are currently running the I2C clock
signal at
100MHz, and our wire lengths are significant on the order of 2-3ft.
Thanks,
Chris Jakubiec
