The 802.3 required inter-packet gap (IPG) is 24 GMII clocks (96 bit times) for 10/100 Mbit modes, and 12 GMII clocks (96 bit times) for 1000 Mbit mode. However, the MAC can tolerate a reduced IPG (2 GMII clocks in 10/100 mode and 5 GMII clocks in 1000 mode) with a correct preamble and start frame delimiter.
This interval between frames must comprise (in the following order):
