ATX PLL Generates TX serial clocks for the 25G transceiver.
Client logic Consists of:
  • Traffic generator, which generates burst packets to the 25G Ethernet Intel® FPGA IP core for transmission.
  • Traffic monitor, which monitors burst packets that are coming from the 25G Ethernet Intel® FPGA IP core.
Source and Probe Source and probe signals, including system reset input signal, which you can use for debugging.
Design Components for the IEEE 1588v2 Feature
Sampling PLL Generates the clocks for the IEEE 1588v2 design components.
  • latency_sclk: 156.25 MHz for latency measurement.
  • sampling_clk: 250 MHz for ToD synchronization
Time-of-day (ToD) Sync Synchronizes the 25G ToD.
ToD Tx ToD for transmit paths for the 25G transceiver.
ToD Rx ToD for receive paths for the 25G transceiver.
Master Precision Time Protocol (PTP) Master PTP consists of a packet generator and a packet receiver.
  • Packet generator: Obtains timestamp information from the 25G Ethernet Intel® FPGA IP core and generates Avalon® streaming packets such as Sync packet and Delay Response packet.
  • Packet receiver: Obtains the delay request packet information from the 25G Ethernet Intel® FPGA IP core and produces timestamp values.
Slave PTP Slave PTP consists of a packet generator, a packet receiver, and a packet compute.
  • Packet generator: Obtains timestamp information from the 25G Ethernet Intel® FPGA IP core and generates Avalon® streaming packets such as Delay Request packet.
  • Packet receiver: Obtains the Sync and Delay Response packets information from the 25G Ethernet Intel® FPGA IP core and produces timestamp values.
  • Packet compute: Calculates and produces the delay and offsets value based on the timestamp values.
2 The 25G Ethernet single-channel design example with IEEE 1588v2 feature only supports 96-bit timestamp format.
