Parameter
Parameter
8.2.7 100BASE-TX Transmit Packet Deassertion Timing
Note: Deassertion is determined by measuring the time from the first rising edge of TX_CLK occurring after the deassertion of TX_EN to the first bit of the “T”
8.2.8 100BASE-TX Transmit Timing (t
Note: Normal Mismatch is the difference between the maximum and minimum of all rise and fall times
Note: Rise and fall times taken at 10% and 90% of the +1 or -1 amplitude
code group as output from the PMD Output Pair. 1 bit time = 10 ns in 100 Mb/s mode.
