Programmable Inter Packet Gap (IPG)

The Ethernet 10G MAC core features a programmable IPG where you can configure any value between 9 octets and 15 octets. Based on your settings on the programmable IPG, the minimum gaps are inserted between the frames. The IPG implementation is illustrated in Figure 1.

Note: For the 2025.1 release and later, the PREAMBLE may start at Octet 0 or Octet 4 based on the user defined Programmable Inter Packet Gap.
