165 / 200 page  SPEAr1340 Timing characteristics Doc ID 023063 Rev 4 165/200 5.7.2 GMII receive timing characteristics The timing characterization is performed assuming an input transition of 2 ns on all the inputs and using MAC_RXCLK as source of clock for GMII RX interface timings extraction. Figure 26. GMII RX timing waveform 5.7.3 MII transmit timing characteristics The timing characterization is performed assuming an output load capacitance of 10 pF on the output pads and using a 2 ns transition on MAC_TXCLK for interface timings extraction. These timings are valid for 10 and 100 Mbps operation. Figure 27. MII TX timing waveform Table 74. GMII RX timing characteristics Parameter Description(1) 1. Characterizations based on external clock sources are performed assuming an ideal 50% duty cycle clock.
