RMII Interface Timing
This section specifies the RMII interface timing for P0_OUTCLK input and output modes. Please refer
to
Note 14.20 Timing was designed for system load between 10 pf and 25 pf.
P0_OUTCLK period
P0_OUTCLK high time
P0_OUTCLK low time
P0_OUTD[1:0], P0_OUTDV output valid from
rising edge of P0_OUTCLK
P0_OUTD[1:0], P0_OUTDV output hold from
rising edge of P0_OUTCLK
P0_IND[1:0], P0_INDV setup time to rising edge
of P0_INCLK
P0_IND[1:0], P0_INDV input hold time after
rising edge of P0_INCLK
