DP83850CVF 技术参数

6.0 A.C. and D.C. Specifications (Continued)

6.2.4 Inter Repeater Collision Timing

Description

Min Max Units

IR_VECT[4:0] change to /IR_COL_OUT assertion[de-assertion]⁹

T19

T20 /IR_COL_OUT assertion to IRD_ODIR de-assertion

/ACTIVEO low to IR_VECT[4:0] feedback^10,11

T20A

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.

6.2.5 Management Bus - Output Mode Timing

Description

T21 /M_DV assertion [de-assertion] from M_CK high

T22 MD[3:0] or /M_ER valid from M_CK high

T23 Removed
