PHY
  • The Transceiver Native PHY Intel® Arria® 10/ Intel® Cyclone® 10 FPGA IP configured for the 10GBASE-R protocol.
  • The preset sets the PHY's TX FIFO MODE to Phase Compensation and RX FIFO MODE to 10GBASE-R.
Transceiver Reset Controller The Transceiver PHY Reset Controller Intel® FPGA IP . Resets the transceiver.
Address decoder Decodes the addresses of the components.
Reset synchronizer Synchronizes the reset of all design components.
IOPLL Generates 312.5 MHz and 156.25 MHz clocks to the MAC IP, reset synchronizer, Ethernet traffic controller, address decoder, and FIFO.
ATX PLL

Generates a TX serial clock for the Intel® Cyclone® 10 GX 10G transceiver.

FIFO
  • Avalon® streaming single-clock FIFO.
  • Buffers the RX and TX data between the MAC IP and the client.
