6.0 A.C. and D.C. Specifications
6.2.4 Inter Repeater Collision Timing
Note 9: This timing refers to the condition where the repeater has detected a change from its driven arbitration vector to
what is seen on the IR_VECT[4:0] bus. In other words, an “Inter Repeater” collision is occurring.
Note 10: This timing refers to the condition where the DP83850C first drives its vector onto IR_VECT[4:0] at the begin-
ning of a packet. The IR_VECT[4:0] feedback (possibly returning from an external bus) must be stable by this time.
Note 11: Guaranteed By Design.
