1.2. Overview

The F-Tile CPRI PHY Intel® FPGA IP block diagram shows the main blocks, and internal and external connections for each variant.
Figure 1. IP Block Diagram
  • The RS-FEC block is optional for the IP core variations that target 10.1376, 12.1651, and 24.33024 Gbps CPRI line rate.
  • The soft reset controller implements the reset sequence of the IP core.
  • The IP variation with 1.2288, 2.4576, 3.072, 4.9152, 6.144, and 9.8304 Gbps CPRI line rate include 8b/10b soft PCS.
  • The IP variations that target CPRI line rates of 10.1376, 12.1651, and 24.33024 Gbps use 64b/66b hard PCS within the F-tile.
  • It supports latency measurement for delay calculation between the FPGA pins to the core.
