Communication timing portfolio expanded for 4G/5G radio

Renesas Electronics Corporation has expanded its communication timing portfolio with three new low phase noise, high-frequency RF timing solutions for 4G and 5G radio, and two new Winning Combinations to meet the requirement for full signal chain solutions. The new 8V19N850 radio synchroniser and 8V19N880, 8V19N882 JESD204B/C clock jitter attenuators provide ITU-T compliant network clock synchronisation best-in-class phase noise, and high clock frequency.

“Network synchronisation plays an increasingly crucial role in the transition to 5G,” said Bobby Matinpour, vice president of Timing Products, Data Center Business Division at Renesas. “With these latest devices and our new Winning Combinations, we enable our communications customers to introduce next-generation solutions with superior performance and reliability.”

The 8V19N850 radio synchroniser is the industry’s first integrated 5G radio synchronisation solution. It is furnished with a complete set of features for radio synchronisation on a single chip, comprising 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 fronthaul synchronisation demands, making it ideal for employment in emerging 5G O-RAN networks for Radio Units (O-RU).

The clock jitter attenuators provide low phase noise and outstanding jitter performance as low as 74fs RMS and -90dB spurious attenuation for mission-critical industrial data converter applications in instrumentation, wireless radio, test and measurement, and high-performance imaging. The new devices support frequencies up to 3932.16MHz (up to 6GHz with an external VCO) and feature 16 and 18 integrated differential outputs to provide a first-in-class balance of high performance, low voltage, and low power consumption with 1.8V support.
