interframe gap (IFG)

An interframe gap (IFG) is a time safety distance between two consecutive data blocks on a network or a fieldbus.

  1. In classic Ethernet with 10 Mbit/s, the interframe gap (IFG) is the minimum distance between two consecutive frames. To ensure that rapidly successive data blocks can be clearly distinguished by the receiving devices, a minimum gap of 96 bits is provided, which at 10 Mbit/s corresponds to a time span of 9.6 ┬Ás. For Gigabit Ethernet, the interframe gap is 96 ns.

  3. For fieldbuses that usually operate in master-slave mode, the interframe gap (IFG) can be constant or variable. For example, it is variable for the LIN bus, but constant for the TTP/A bus.
