Mix and Match Example
In the Arria 10 transceiver architecture, the separate Native PHY IP core and the PLL IP core scheme
allows great flexibility. It is easy to share PLLs and reconfigure data rates. The following design example
illustrates PLL sharing and both bonded and non-bonded clocking configurations.
