REF_CLK clock period
REF_CLK duty cycle
REF_CLK peak-to-peak jitter
Rise time REF_CLK (20%–80%)
Fall time REF_CLK (80%–20%)
REF_CLK to RMII data TXD[1:0], TX_EN delay
Note:
1. The symbols used for timing specifications follow the pattern of t
inputs and t
timing (MT) for the time t
the clock reference symbol representation is based on two to three letters representing the clock of a particular functional.
For example, the subscript of t
used with the appropriate letter: R (rise) or F (fall).
