2.5.2. TX and RX Latency
The TX and RX latency values are based on the following definitions and assumptions:
- TX latency is the time taken for the data frame to move from the Avalon® streaming interface to the PHY-side interface.
- RX latency is the time taken for the data frame to move from the PHY-side interface to the Avalon® streaming interface.
- No backpressure on the Avalon® streaming TX and RX interfaces.
- All options under Legacy Ethernet 10G MAC interfaces, that allow compatibility with the legacy MAC are disabled.
