Signals of MAC and PHY Variations With Adapters
Most signals of the 40-100GbE IP core with adapters are identical to the signals for the IP core without
adapters. The IP core variations with adapters have the following differences:
• On the transmit side, in TX-only and duplex variations, the TX Avalon-ST client interface signals
replace the TX custom streaming client interface signals.
• On the receive side, in RX-only and duplex variations, the RX Avalon-ST client interface signals
replace the RX custom streaming client interface signals.
