Semiconductor industry's first: PHY SoC for 5GNR/LTE small cell Open RAN radio

5G open RAN baseband semiconductor and software specialist Picocom launched semiconductor chip industry's first SoC optimised for 5G small cell Open RAN radio units (O-Rus). The PC805 small-footprint, low-power SoC supports flexible RF/bandwidth mapping and can be used for designing enterprise, industrial, neutral host and private networks. Packaged in a 17mm x 17mm FC LFBGA Flip-Chip BGA, PC805 chip significantly reduced bill of materials compared to current designs, claims Picocom.
This chip interface directly with O-Dus via Open Fronthaul (split 7.2) and supports seamless connections to RFICs with a standardised JESD204B high-speed serial interface. PC805 is shipped with a fully integrated O-RAN compliant Picocom 5G NR RU and M-plane software suite. The key features include: Picocom’s 5GNR and LTE low PHY software O-RAN eCPRI Open Fronthaul interface On-chip supervisor Linux CPU for M-plane, S-plane processing, and radio control Fourier transforms: FFT, iFFT Digital Front End (DFE) Digital Pre-Distortion (DPD) Crest Factor Reduction (CFR) Simple cascade mode for eCPRI use cases PRACH processing IQ compression/decompression Secure on-chip boot capability Debug and device monitoring The key interfaces include: ...
