One of the biggest 5G network deployment challenges is synchronizing higher volumes of more densely packed base stations. Another is keeping services operating through Global Navigation Satellite System (GNSS) lapses due to vulnerabilities such as jamming, spoofing or loss of signal. Microchip Technology Inc., via its Microsemi subsidiary, is solving these and other challenges for networks with additions to its Precision Time Protocol (PTP) PackeTime® portfolio including the TimeProvider 4100 Release 2.0. The TimeProvider release adds 10 Gigabit Ethernet (GE) 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.
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 ITU-T Class C & D boundary clock standards. These standards dictate 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. 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.
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 (Europe), QZSS (Japan) 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.
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 broad family of precise timing systems.
Microchip’s TimeProvider 4100 2.0 and IGM 3.0 1588v2 PTP Grandmasters are available now. The TimeProvider 4100 2.0 expansion module and three IGM Plus models with enhanced features can be ordered separately. Customers with a valid annual maintenance and support agreement can load software options and upgrades for TimeProvider 4100 2.0 onto existing hardware models. The company also offers a variety of support services spanning hardware and software repair, maintenance, updates and upgrades, along with options for adding new capabilities through hardware modules and licensed software.
