Picocom recently introduced the PC805, claiming the industry’s first system-on-chip (SoC) optimized for 5G small cell Open RAN radio units (O-RUs). The small footprint, low-power 5G O-RU SoC is designed to ease the implementation of 5G NR/LTE small cell O-RUs for use cases such as enterprise, industrial, neutral host, and private networks.

Simplifying the design of O-RUs, the PC805 PHY SoC meets Open RAN specifications and interfaces with an O-DU (as part of an Open RAN split 7.2) via an Open Fronthaul eCPRIi interface. It supports seamless connections to RFICs with a JESD204B high-speed serial interface.
An external processor/controller for configuration is not necessary. Configuration is performed via an integrated RISC-V based management processor running a Linux OS, Picocom said.
The PC805 performs aggregation of four or more 4T4R carriers at a 200-MHz instantaneous bandwidth (IBW) and is operational in U.S. CBRS and equivalent bands that are rapidly becoming available in other countries. A single PC805 supports multiple bands, including both TDD and FDD for 5G NR and LTE, with a cascade of two SoCs doubling the bandwidth supported.
The PC805 is available in a 17 × 17-mm FC LFBGA form factor. Samples will be available to lead customers, starting in November 2023. The PC805 launch includes a complete software suite and an RU demonstrator board (PC805RDB), which is a flexible 5G NR/LTE radio unit board used to demonstrate the PC805 SoC with an onboard RF transceiver, front-end and associated support circuitry, and software.
Picocom recently partnered with Texas Instruments on a 5G O-RAN outdoor RU reference design that leverages Picocom’s PC802 PHY SoC and TI’s AFE7769D transceiver.
