User Guide
■ Supports synchronous buffer or simple FIFO synchronization modes for
externally clocked antenna-carrier interfaces.
■ Supports independent sample rates for each antenna-carrier interface.
■ Supports 15- and 16-bit data sample widths on uplink and downlink using
the Altera Avalon Streaming (Avalon-ST) interconnect specification.
Device Family Support
Table 1–1 defines the device support levels for Altera IP cores.
Table 1–2 lists the level of support offered by the CPRI IP core for each Altera device
family.
Table 1–3 shows the slowest device family speed grade that supports each CPRI line
rate in each device family. Lower speed grade numbers correspond to faster devices.

Preliminary support—The IP core is verified with preliminary timing models for this device family.
The IP core meets all functional requirements, but might still be undergoing timing analysis for the
device family. It can be used in production designs with caution.
Final support—The IP core is verified with final timing models for this device family. The IP core
meets all functional and timing requirements for the device family and can be used in production
designs.
