Microchip Technology Inc., via its Microsemi subsidiary, has added the TimeProvider 4100 Release 2.0 to its Precision Time Protocol (PTP) PackeTime portfolio.

TimeProvider keeps services operating through GNSS lapses due to vulnerabilities such as jamming, spoofing or loss of signal. It is also designed to meet one of the biggest 5G network deployment challenges —synchronizing higher volumes of more densely packed base stations.

Microchip is also introducing Release 3.0 to its Integrated GNSS Master (IGM) family.

TimeProvider 4100. Release 2.0 adds 10 Gigabit Ethernet support, a boundary clock operation mode that lowers operational costs, and other enhancements to improve how timing flows are distributed from multiple sources to a network’s base stations and other endpoints.

The 72-channel GNSS receiver coupled with Microsemi’s patented active thermal compensation technology provides excellent accuracy of <10 ns RMS to UTC (USNO). With the time source provided through GNSS satellite input, it is essential to provide flexible support for constellations of choice depending on the region. TimeProvider 4100 supports GPS, GLONASS, BeiDou, Galileo, QZSS, and SBAS in its standard version.

TimeProvider 4100 2.0 with its 10 GE expansion module has been selected by SK Telecom in Korea for its delivery of 5G services in the Seoul metropolitan area and Chungcheong province.

IGM 3.0. For service providers that need to deploy more compact PTP 1588 v2 Grandmasters to fewer base stations closer to the network’s edge, Microchip is also introducing Release 3.0 to its Integrated GNSS Master (IGM) family.

IGM 3.0 combines an IEEE-1588v2 PTP grandmaster with a GNSS receiver and antenna to simplify indoor or outdoor installations. Each of the three IGM 3.0 additions deliver precise time and phase as well as new capabilities enabled by IGM Plus hardware models with enhanced oscillators and GNSS receivers.

The new oscillator options extend time-keeping holdover performance while the enhanced receiver speeds satellite signal acquisition and improves security by accessing more GNSS constellations simultaneously.

The receiver upgrade option supports GPS, Galileo, QZSS and GLONASS, and is Beidou-ready. The IGM 3.0 software includes higher PTP capacity to 60 clients along with IPv6 support for traffic and management flows.

TimeProvider’s Gateway Clock. Extending the TimeProvider 4100’s Gateway Clock operation mode with Microchip’s high-performance boundary clock (HP-BC) operation mode enables it to support the latest high-accuracy ITU-T Class C & D boundary clock standards. These standards dictate extremely accurate time transfer over optical networks so operators can use dense wavelength division multiplexing (DWDM) technology rather than dedicated fiber.

Release 2.0 accommodates escalating bandwidth requirements of next-generation network devices through an optional expansion module that provides 10 GE interfaces. Expanded monitoring functions enable service providers to understand how time and phase performance is affected by network elements, the company added.

PTP client capacity has been increased to 790 to provide the scalability that is critical for deployments in mobile network aggregation layers and new DOCSIS 3.1 Remote-PHY cable architectures.

Both TimeProvider 4100 Release 2.0 and IGM Release 3.0 are managed with TimePictra, the centralized and unified management platform for the company’s family of precise timing systems.
