Note:
1. The symbols used for timing specifications 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, t
MRDVKH
symbolizes MII receive
timing (MR) with respect to the time data input signals (D) reach the valid state (V) relative to the t
MRX
clock reference (K)
going to the high (H) state or setup time. Also, t
MRDXKL
symbolizes MII receive timing (GR) with respect to the time data input
signals (D) went invalid (X) relative to the t
MRX
clock reference (K) going to the low (L) state or hold time. Note that, in general,
the clock reference symbol representation is based on three letters representing the clock of a particular functional. For
example, the subscript of t
MRX
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).
