4.2.1.4. Clock Domains

The Physical layer's buffers implement clock domain crossing between the Avalon® system clock domain and the Physical layer's clock domains.

In systems created with Platform Designer (Standard), the system interconnect manages clock domain crossing if some of the components of the system run on a different clock. For optimal throughput, run all the components in the datapath on the same clock.

Note: All of the clock inputs for the Logical layer modules must be connected to the same clock source as the Avalon® system clock.
