Parameter
Parameter
15.2.9 100BASE-TX 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.
15.2.10 100BASE-TX 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 deassertion of Carrier Sense.
Note: 1 bit time = 10 ns in 100 Mb/s mode.
