Network synchronisation chip for 5G radio access equipment

25 August 2021 Telecoms, Datacoms, Wireless, IoT

5G technology requires time sources to be synchronised throughout a packet-switched network 10 times more accurately than 4G requirements. Microchip Technology now makes it possible to achieve 5G performance with the first single-chip, highly integrated, low-power, multi-channel IC coupled with the company’s widely adopted and reliable IEEE 1588 Precision Time Protocol (PTP) and clock recovery algorithm software modules.

Microchip’s ‘measure, calibrate and tune’ capabilities ensure 5G systems achieve ITU-T standard G.8273.2 Class C (30 ns max|TE|) and the emerging Class D (5 ns max|TEL|) time error requirements. The architecture provides flexibility, offering up to five independent digital phase locked loop (DPLL) channels while consuming only 0,9 W of power in a compact 9 x 9 mm package.

With five ultra-low-jitter synthesisers, this latest platform offers 100 fs RMS jitter performance required by high-speed interfaces in the latest 5G RU, DU and CU systems.
