JAJSBK7H January 2012 – February 2018 DS125DF410
The INT line is an open-drain, 3.3V tolerant, LVCMOS active-low output. The INT lines from multiple DS125DF410s can be wired together and connected to an external controller.
The Horizontal Eye Opening/Vertical Eye Opening (HEO/VEO) interrupt can be enabled using SMBus control for each channel independently. This interrupt is disabled by default. The thresholds for horizontal and vertical eye opening that will trigger the interrupt can be set using the SMBus control for each channel.
If any interrupt occurs, registers in the DS125DF410 latch in information about the event that caused the interrupt. This can then be read out by the controller over the SMBus.
