Note:
1.The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state)
(reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMRDVKH
symbolizes MII receive timing (MR) with respect to the time data input signals (D) reach the valid state (V) relative to
the tMRX clock reference (K) going to the high (H) state or setup time. Also, tMRDXKH symbolizes MII receive timing
(GR) with respect to the time data input signals (D) went invalid (X) relative to the tMRX clock reference (K) going to
the high (H) state or hold time. Note that, in general, the clock reference symbol representation is based on two to
three letters representing the clock of a particular functional. For example, the subscript of tMRX represents the MII
(M) receive (RX) clock. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F
(fall).
2.Signal timings are measured at 0.7 V and 1.9 V voltage levels.
3.Guaranteed by design.
