Renesas addresses network synchronisation for 4G/5G radio
Communication timing options from Renesas Electronics now include three low phase noise, high frequency RF timing devices for 4G and 5G radio. The 8V19N850 radio synchroniser and 8V19N880, 8V19N882 JESD204B/C clock jitter attenuators deliver ITU-T-compliant network clock synchronisation. They are also claimed to have best-in-class phase noise and high clock frequency.
The 8V19N850 radio synchroniser is claimed to be the industry’s first integrated 5G radio synchronisation device. It is equipped with a complete set of features for radio synchronisation on a single chip, including full ITU-T G.8273.2 T-BC/T-TSC Class C, ITU-T G.8262.1 enhanced SyncE, and JESD204B/C compliance. The 8V19N850 also takes care of recovering the clock from CPRI/eCPRI, per IEEE 802.1cm front haul synchronisation requirements, making it suitable for use in emerging 5G O-RAN networks for radio units (O-RU).
The 8V19N880 and 8V19N882 JESD204B/C clock jitter attenuators deliver low phase noise. They offer jitter performance as low as 74fs RMS and -90dB spurious attenuation for mission-critical industrial data converter applications in wireless radio, test and measurement, instrumentation, and high performance imaging. They support frequencies up to 3932.16MHz (up to 6GHz with an external VCO) and feature 16 and 18 integrated differential outputs with low power consumption and 1.8V support.
The devices are also featured in Renesas’ two Winning Combinations, designed to address increasing demand for higher bandwidth for cellular services. The Small Cell Radio and MIMO Radio Combinations use mutually compatible devices for lower risk and faster time to market. They also showcase the combined benefits of the new RF timing ICs paired with Renesas’ complementary microcontroller and power management offerings to accelerate solution design.
The 8V19N850, 8V19N880 and 8V19N882 RF timing ICs are available now.
