The common features of the PC-CFR core and individual configuration features of both implementations of PC-CFR (using PL resources only and using DFE-CFR + PL resources) are as follows:

  • Support for multiple air interface standards.
  • Smart Peak Processing mode for supporting wide transmit bandwidth up to 400 MHz for DFE-CFR and up to 600 MHz for PL only, processes incoming samples at >1.2 times instantaneous bandwidth (iBW) reducing resource utilization.
  • Support for power and frequency dynamics.
  • Support for dynamic computation of cancellation pulse (CP).
  • Meets performance requirements (EVM, PAPR, and ACLR) of all air interfaces.
  • A maximum of five different RATs are supported. The total number of carriers using all RATs is 30. LTE 5 MHz and LTE 10 MHz are considered different RATs because the corresponding base pulses are different.
  • Support for datapath delay matched TUSER forwarding feature.
  • Support for cancellation pulse read back in static mode and base pulse read back in dynamic mode.
  • Support for read back of CFR configuration and statistics registers.
Important: The core's control interface address format is modified to support 8 MB of space. When upgrading from older core versions, adopt the new control interface address map mentioned in the PC-CFR LogiCORE IP Product Guide (PG097) (registration required).
