8.2.9 100BASE-TX MII Receive Packet Latency Timing
Note: Carrier Sense On Delay is determined by measuring the time from the first bit of the “J” code group to the assertion
of Carrier Sense.
Note: 1 bit time = 10 ns in 100 Mb/s mode
Note: PMD Input Pair voltage amplitude is greater than the Signal Detect Turn-On Threshold Value.
8.2.10 100BASE-TX MII Receive Packet Deassertion Timing
Note: Carrier Sense Off Delay is determined by measuring the time from the first bit of the “T” code group to the deasser-
tion of Carrier Sense.
Note: 1 bit time = 10 ns in 100 Mb/s mode
