Receiver inputs are 96k
minimum resistance, which is 1/8 unit load.
60s test result is guaranteed by correlation from 1s result.
VISOis the voltage difference between GND1 and GND2.
The maximum data rate is specified using the maximum jitter value according to the formula: data rate = 1 / (4tJ). See the
Skew
section for more information.
Initial startup time is the time for communication to recover after a fault condition. Internal communication timeout fault time
is the time before a fault is indicated on
RE
, after internal communication has stopped.
Bd = 2 bits.
