6.4.6 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: RD± voltage amplitude is greater than the Signal Detect Turn-On Threshold Value.
6.4.7 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 deasser-
tion of Carrier Sense.
Parameter Description Notes Min Typ Max Units
T4.6.1 Carrier Sense ON Delay 17.5 bit times
T4.6.2 Receive Data Latency 21 bit times
Parameter Description Notes Min Typ Max Units
T4.7.1 Carrier Sense OFF Delay 21.5 bit times
