8.2.5 100 Mb/s MII Receive Timing
Note: RX_CLK may be held low or high for a longer period of time during transition between reference and recovered
clocks. Minimum high and low times will not be violated.
8.2.6 100BASE-TX Transmit Packet Latency Timing
Note: For Normal mode, latency is determined by measuring the time from the first rising edge of TX_CLK occurring after
the assertion of TX_EN to the first bit of the “J” code group as output from the PMD Output Pair. 1 bit time = 10 ns in 100
Mb/s mode.
