For today’s critical infrastructure providers — 5G wireless networks, smart grids, data centers, cable and transportation services — a fundamental need exists for a redundant, resilient and secure precise timing and synchronization solution.

Microchip Technology Inc.’s TimeProvider 4100 Release 2.2 grandmaster provides a new level of resiliency with the introduction of an innovative redundancy architecture in addition to support for a multi-band GNSS receiver and enhanced security to ensure always-on precise timing and synchronization.

Redundancy is key for infrastructure providers to ensure uninterrupted services. Infrastructure deployments previously relied on hardware redundancy to avoid service disruption despite costly modular architectures. Microchip’s TimeProvider 4100 Release 2.2 grandmaster provides redundancy via software implementation, enabling flexible deployment and lower hardware costs without sacrificing ports.

In addition, the TimeProvider 4100 Release 2.2 grandmaster introduces an increased level of resiliency by supporting a new GNSS multi-band, multi-constellation receiver to protect against time delay resulting from space weather, solar events and other disruptions that may impact critical infrastructure services.

Multi-band GNSS is particularly important for the highest levels of accuracy, including primary reference time clock class B (PRTC-B, 40 ns) and enhanced primary reference time clock (ePRTC, 30 ns).

With a focus on security solutions across its technology portfolio, Microchip’s new TimeProvider 4100 Release 2.2 grandmaster adds support for RADIUS and TACACS+ as well as new anti-jamming and anti-spoofing capabilities.

“Resilient, redundant and secure precise timing and synchronization solutions are necessary to mitigate security risks to critical infrastructure,” said Randy Brudzinski, vice president and general manager of Microchip’s frequency and time business unit. “This latest release brings an innovative software redundancy that enables always-on technology as well as support for multi-band GNSS to eliminate ionospheric time error delays. It provides new key security, anti-jamming and anti-spoofing so critical infrastructure services can be accessed only by authorized, authenticated personnel.”

In addition, the TimeProvider 4100 Release 2.2 grandmaster provides a super oven controlled crystal oscillator (OCXO) option for enhanced holdover capabilities in case of GNSS disruption.

The TimeProvider 4100 Release 2.2 grandmaster is a family of products with hardware expansion modules for legacy fan-out or Ethernet fan-out with 10 Gigabit Ethernet support. It can be configured in specific operation modes to act either as a gateway clock, a high-performance boundary clock or an ePRTC.

The TimeProvider 4100 Release 2.2 grandmaster embeds additional Microchip technology including its OCXO, super OCXO, rubidium atomic clock, field-programmable gate arrays (FPGAs), Ethernet switch, synthesizers and cleaning oscillators.

The TimeProvider 4100 is part of Microchip’s Virtual Primary Reference Time Clock (vPRTC) product portfolio, offering end-to-end precise time and synchronization solutions. These include Cesium atomic clocks for source of frequency and time, the BlueSky GNSS Firewall for security, TimeProvider 4100 high-performance boundary clock and TimeProvider 4100 Gateway clocks, as well as the TimePictra software suite, which manages the end-to-end precise time architecture across all Microchip timing products.

Microchip’s TimeProvider 4100 Release 2.2 grandmaster offers several options for software and hardware support including installation, sync audits, network engineering and 24/7 worldwide support. It is available now for both new and already-deployed systems.

Microsemi timing module designed for IEEE 1588 protocols
Microsemi Corporation has launched a new IEEE 1588 timing synchronization module, offering a complete self-contained platform for customers to implement IEEE 1588 network timing client protocols.

The solution, which consists of hardware, firmware and software, combines capabilities from Microsemi’s broad product portfolios by leveraging the company’s SmartFusion2 system-on-chip (SoC) field programmable gate array (FPGA), ZL30363 IEEE 1588 phase-locked loop (PLL) and VSC8575 Ethernet PHY devices.

Microsemi’s new IEEE 1588 timing synchronization module streamlines customers’ developments to add synchronization network timing to their designs, simplifies the sourcing process and reduces development time while providing an easy integration.

The module also includes drivers, servos/algorithm firmware, IEEE 1588 Precision Time Protocol (PTP) stack software, a user guide and reference board schematics to deliver a fully tested chip-set solution from a trusted tier-one vendor.

The IEEE 1588 timing synchronization module blends Microsemi’s expertise in nanosecond-level accurate timestamping for IEEE 1588 via the VSC8575 Ethernet PHY; embedded IEEE 1588 protocol engine and servo via its SmartFusion2 SoC FPGA host processor; and high precision clock generation, holdover and reference switching via its ZL30363 system synchronizer.

The solution is addressed via a command line interface to minimize software integration efforts.

The combination of these capabilities makes the new solution suitable for applications within the industrial networking, smart grids, communications, defense and data center markets.
