ALISO VIEJO, CA -- Microsemi Corporation has quadrupled the Precision Time Protocol (PTP) client capacity of its TimeProvider 2700 PTP grandmaster (GM) clock and TimeProvider 2300 edge master clock that provides synchronization to LTE networks. The device now provides simultaneous hardware time stamping support of up to 512 PTP clients, resulting in a significant cost benefit using a single GM clock. In addition, the clock now provides ITU Telecommunication Standardization Sector (ITU-T) G.8275.1 PTP phase profile support to address stringent synchronization requirements.
Microsemi's enhanced TimeProvider 2700/2300 clocks raise the bar for client capacity available from a single PTP GM device targeted at the LTE market, offering increased client capacity from 128 PTP clients to 512 PTP clients. The additional G.8275.1 PTP phase profile support has been enabled with a new software update, which is ideal for customers in the communications market seeking to upgrade their LTE networks with the latest synchronization capabilities. Both upgrades are available on new as well as deployed TimeProvider 2700/2300 clocks, without additional hardware.
"As a market leader delivering high value PTP grandmaster clocks, we are pleased to announce our higher client capacity, which further facilitates ease of deployment for our TimeProvider 2700/2300 clocks with significantly improved scalability and future network growth capabilities for customers," said Barry Dropping, director of product management for Microsemi's Frequency & Timing division. "The additional G.8275.1 PTP profile for phase not only increases flexibility and utility, but is also supported by our timing PTP chipsets, complementing Microsemi's other product offerings to deliver complete end-to-end timing solutions."
Microsemi's 512 PTP client capacity capabilities meet the evolving client density requirements as LTE networks scale up with the ever-increasing base station and small cell deployments worldwide. Microsemi's devices can manage the increased client count at full PTP message rate, resulting in no potential compromise in end-to-end accuracy which can be the case with alternative solutions that limit the PTP timing message rates at higher client counts. With more Microsemi customers now requiring support for the G.8275.1 PTP profile for phase as they plan for LTE-TDD and LTE-A network deployments, the company's latest enhancement for the TP2300/2700 family will help ensure their networks are well-equipped for continued growth.
According to the Global Mobile Suppliers Association (GSA), 79 carriers in total have launched, deployed or are trialing LTE Advanced technologies in their networks. The GSA also said 21 operators have launched LTE Advanced carrier aggregation in 14 countries. With IEEE 1588 solutions deployed globally in more than 350 networks, and the company's SyncWorld® Ecosystem Program, Microsemi is committed to delivering the industry's most comprehensive synchronization solutions for these 4G/LTE networks.
Microsemi's TimeProvider series features the industry's first offering of optimized synchronization solutions that deliver precise time from the core to the network edge, supporting the rapid transition to Ethernet mobile backhaul, and improving the mobile service experience for end users. With full support of International Telecommunications Union (ITU) approved PTP profiles for frequency and phase synchronization, and superior client capacity scalability, the TimeProvider series enables wireless operators to seamlessly migrate their networks forward to assure high quality service for LTE and small cell deployments.
About Microsemi's Carrier Class PTP Clock Portfolio
Microsemi builds the leading-edge embedded IEEE 1588 PTP slave clocks and boundary clocks designed into a wide range of base stations, small cells and PTP aware switching equipment. End-to-end synchronization management of all clocks is completed with Microsemi's TimePictra software, which now extends beyond Microsemi clocks to include supporting the monitoring of third party PTP slave clocks. Sync monitoring is ideal for closely observing and tracking the end-to-end synchronization chain, including embedded boundary clocks, end-point slave clocks found in on path switching elements and end point base stations or small cells.
Some of the products offered include the TimeProvider series, which features IEEE 1588 PTP GMs that enable communications service providers to build an accurate, robust and reliable network timing infrastructure. The TimeProvider 5000 is optimized for high PTP client capacity and full redundancy from the core supporting both ITU-T G.8265.1 and ITU-T G.8275.1 profiles.
The TimeProvider 2700 Edge Grandmaster Clock and TimeProvider 2300 Edge Boundary Clock provide synchronization in the mobile backhaul network and small cell aggregation locations. These edge master clocks are optimized to help enable cost effective deployments, mitigate asymmetric timing errors and meet the stringent synchronization requirements of 4G/LTE networks.
The new indoor Integrated GNSS Master IGM-1100i provides synchronization for in-building, convenient and cost-effective deployments at the very outside edge of the network. Eliminating the need for external GPS antennas and deployed with Power-over-Ethernet, the IGM-1100i is a breakthrough technology for small cell synchronization.
Microsemi's TimeProvider 2700 PTP GM clock and TimeProvider 2300 edge master clock are both available now.
