Brand newPC805As the first in the industry to support 25Gbps System-on-chip ( and CPRI fronthaul interfaces) >), removing barriers to low-cost open RF unitsSoC
Beijing, China, 2023Year11Month - < /span> 5G open RAN baseband chip and carrier-grade software provider Picocom today announced the launch of a new, fully optimized PC805 system-on-chip (SoC) to help the industry further enhance 5G Performance of small cell open RAN radio units (O-RU). This highly integrated, small-sized, low-power SoC chip has a fronthaul rate of up to 25Gbps and is designed to simplify the design and production of 5G NR/LTE small base station O-RU. It can support both CPRI and eCPRI interfaces and include China The world's major 5G NR/LTE frequency bands further facilitate the deployment of small base stations in various application scenarios, including enterprise, industrial, third-party neutral operators and private network application scenarios.
Compared with existing solutions, using PC805 can greatly simplify the O-RU design process and significantly reduce material costs. PC805 SoC directly interfaces with the distributed unit (O-DU) through the open fronthaul interface (Split 7.2 or Split 8), and supports seamless connection with the radio frequency unit (RFIC) through the standardized JESD204B high-speed serial interface. While providing the PC805 chip, Bikochi also provides a fully integrated 5G NR RU and management plane (M-plane) software suite that complies with the O-RAN standard.
Jiang Yingbo, CEO of Bikochi, said: "Most existing O-RU products are based on FPGA technology, which requires redesigning hardware to meet the needs of different application scenarios. We need to seize these new opportunities and adopt more Targeted solutions can meet the needs of new scenarios with only simple software changes. This is why I am very happy to introduce to you Bikochi's SoC chip that is optimized for small base station RF units and has full flexibility. PC805 will usher in a new era of small cell deployment and meet customers' growing needs for more carrier aggregation and flexible spectrum utilization."
As 5G deployment advances, operators hope to aggregate spectrum in different frequency bands. This is especially true for third-party neutral operators, who often need to support frequency allocations from multiple mobile operators or aggregate non-contiguous spectrum in shared spectrum. frequency band. PC805 requires only minimal additional components to support these application scenarios, greatly reducing capital expenditures and operating costs. In short, using the PC805 chip plus RF and power, you have a set of O-RU products that can not only meet the needs of the Chinese market, but also support developers to provide diversified O-RU products for the global market.
PC805 can aggregate four or more 4T4R carriers within 200 MHz instantaneous bandwidth (IBW), which is suitable for relevant frequency bands in my country (such as n41 and n78), the US CBRS frequency band and an increasing number of similar frequency bands in other countries/regions (such as the UK n77 shared access band). A single PC805 can also support multiple frequency bands, including TDD and FDD for 5G NR and LTE, and the cascading of two PC805 SoCs can double the supported bandwidth. The O-RU solution using PC805 can also be customized for different market configurations. For example, it can be configured as a CPRI interface widely used in the Chinese market, thus supporting Split 8 to achieve a wider range of applications.
Launched with the PC805 is a complete software suite and accompanying RU demonstration board PC805RDB to simplify development and accelerate time to market. The PC805RDB is a flexible 5G NR/LTE radio unit (RU) board used to demonstrate the PC805 SoC with onboard RF transceiver, RF front-end and associated supporting circuitry and software.
The PC805 is available in a 17mm x 17mm FC LFBGA flip-chip ball grid form factor, and Picocci will be sampling to major customers starting in November 2023.
