REF_CLK clock
REF_CLK duty cycle
REF_CLK to RMII data TXD[1:0], TX_EN delay
REF_CLK data clock rise time
REF_CLK data clock fall time
Note:
1. The symbols used for timing specifications follow the pattern of t
inputs and t
transmit timing (RMT) for the time t
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 t
convention is used with the appropriate letter: R (rise) or F (fall).
