Microchip has released version 2.3 of the TimeProvider® 4100 primary clock timing and synchronization system, which is designed to protect critical infrastructure networks.

Microchip's new primary clock product has been enhanced with further functionality, increasing flexibility, security, and scalability in deployment.

Infrastructure communication networks, including 5G mobile, utilities, cable TV, transportation, defense, and data centers, require precise timing signals obtained from the Global Positioning System (GPS) or other global satellite systems. When Global Navigation Satellite System (GNSS) signals are unavailable, these networks need to provide redundant backup systems. To meet this requirement, Microchip (Microchip Technology Inc.) has today introduced the 2.3 version of the TimeProvider® 4100 precision timing master clock product, which incorporates the latest IEEE® 1588 v2.1 security standard and offers higher flexibility and scalability in deployment while protecting the timing system.

The 2.3 version of the Microchip TimeProvider 4100 primary clock introduces an optional licensing feature with ultra-robust Precision Time Protocol (PTP) for multiple clients, allowing customers to connect to up to three other primary clocks within operator networks. This functionality serves as a backup for time and phase inputs. The new feature includes a majority voting mechanism compliant with the latest IEEE 1588 2.1 standard, which enables the selection of the best input for backup protection of the Auxiliary Partial Time Support (APTS).
Additionally, the 2.3 version of the TimeProvider 4100 primary clock supports two PTP server configuration profiles on each Ethernet port, providing greater deployment flexibility. Customers can now optimize the use of these ports without the need for additional hardware. The 2.3 version of the TimeProvider main clock also allows the use of PTP server, PTP client, and in-band management on a single port.
The 2.3 version of the TimeProvider 4100 primary clock supports the latest IEEE 1588 2.1 2019 standard, offering higher security. The new standard includes support for architecture-directed security, using redundant communication paths between PTP nodes to detect tampering behaviors, and it also implements out-of-band management mechanisms for detecting tampering, degradation, and failures. This primary clock product provides comprehensive support for authentication, authorization, and accounting (AAA) and two-factor authentication. As a software update, the 2.3 version of the TimeProvider 4100 is applicable to new systems and existing deployed systems. Other features include:
• PTP enhancements, including an increased capacity of up to 1000 network clients to meet the needs of certain applications (such as data centers).
• Enhancements to the E1/T1 expansion module, including new signals like composite clock and JCC (Japanese CC format), with input and output to facilitate integration with traditional systems.
The 2.3 version of the TimeProvider 4100 can be managed using Microchip's TimePictra® synchronization management system, supporting full fault management, configuration, accounting, performance, and security (FCAPS). For ordering details, please contact Microchip sales personnel.
