CPRI Intel® FPGA IP
CPRI High-Speed Serial Interface
CPRI is a high-speed serial interface for network radio equipment controllers (REC) to receive data from and provide data to remote radio equipment (RE). The CPRI Intel FPGA IP core targets high-performance, remote radio network applications.
You can configure the CPRI Intel FPGA IP core as an RE or an REC.
Features
- Compliant with the Common Public Radio Interface (CPRI) Specification v7.0 (2015-10-09) Interface Specification
- Supports radio equipment controller (REC) and radio equipment (RE) module configurations
- Configurable CPRI line bit rate auto-rate negotiation support using Intel FPGA on-chip high-speed transceivers
- Configurable and runtime programmable synchronization mode: host port or agent port on a CPRI link
- Transmitter (Tx) and receiver (Rx) deterministic latency and delay measurement and calibration. Note: Compliant with the CPRI Specification requirements R-19, R-20, R-20A, R-21, and R-21A

Lower device speed grade numbers correspond to faster devices. The entry -x indicates that both the industrial speed grade Ix and the commercial speed grade Cx are supported for this device family and CPRI line bit rate. Table entries show slowest supported device speed grade/supported transceiver speed grade.
