Microchip’s Multi Channel IC Provides Ultra Precise Timing for 5G Radio Access Equipment712370

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

“Our newest ZL3073x/63x/64x network synchronization platform implements sophisticated measure, calibrate and tune capabilities, thereby significantly reducing network equipment time error to meet the most stringent 5G requirements,” said Rami Kanama, vice president of Microchip’s timing and communications business unit. “A uniquely flexible architecture for implementing the necessary channel density as well as high-performance, low-jitter synthesizers help simplify the design of timing cards, line cards, Radio Units (RU), Centralized Units (CUs) and Distributed Units (DUs) for 5G Radio Access Networks (RAN).”

Microchip’s measure, calibrate, and tune capabilities ensure 5G systems achieve International Telecommunication Union – Telecommunication (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-millimeter package that simultaneously reduces board space, power, and system complexity.

With five ultra-low-jitter synthesizers, this latest platform offers 100 femtoseconds (fs) root mean square (RMS) jitter performance required by high-speed interfaces in the latest 5G RU, DU CU systems.

Microchip’s network synchronization platform software includes its ZLS30730 high-performance algorithm coupled with its ZLS30390 IEEE 1588-2008 protocol engine. Both are widely deployed in 3G, 4G, and 5G networks with precise timing capabilities.

Microchip’s ZL3073x/63x/64x network synchronization platform combines seamlessly with the company’s family of precision 5G oscillators – for example, the OX-601 Oven Controlled Crystal Oscillator (OCXO) – to offer 5G network operators a total system solution.

The company’s extensive portfolio of timing and clock solutions includes clock generation, fanout buffer, jitter attenuator solutions, and quartz and MEMS oscillators complemented by a broad family of Ethernet physical layers (PHY) devices.
