T2.7.1
TX_CLK to PMD Output Pair
Deassertion
Notes
100 Mb/s Normal mode

bits
Note: Deassertion is determined by measuring the time from the first rising edge of TX_CLK occurring after the deasser-
tion of TX_EN to the first bit of the “T” code group as output from the PMD Output Pair. 1 bit time = 10 ns in 100 Mb/s mode.
