6.0 A.C. and D.C. Specifications
6.2 A.C. Specifications
6.2.1 Receive Timing
Note 1: “CRSx” and “RXEx” refer to any of the CRS[11:0] signals. In the event of a collision (more than one CRS is
active) none of the RXE signals will be asserted.
Note 2: If, after 4 RXC clocks from CRSx going high, no aligned data is received, the DP83850C 100RIC will repeat the
JAM pattern.
T0 CRSx to RXEx assertion delay (Note 1)
T1 CRSx to RXEx de-assertion delay with no collision
T2 CRSx to RX_DV delay requirement (Note 2)
T3 /IRD_V setup to IRD_CK high
T4 /IRD_V hold from IRD_CK high
T5 IRD[3:0] or /IRD_ER setup to IRD_CK high
T6 IRD[3:0] or /IRD_ER hold from IRD_CK high
