Microchip TimeProvider 2700 IEEE 1588 PTP 32-channel 50Hz to 60Hz 4G/LTE networks Grandmaster Clock

Overview

Microsemi's TP2700 PTP IEEE-1588v2 Master Clocks are advanced IEEE 1588 Precision Time Protocol (PTP) products that are scaled and optimized for deployment at or near the mobile network edge-solutions that evolve the synchronization distribution architecture without retrofit of existing backhaul equipment or reengineering the network. ® 2300 Edge Boundary Clock is a new type of IEEE 1588 Precision Time Protocol (PTP) equipment designed for deployment in the mobile backhaul network, at macro base station sites, or small cell aggregation locations. These Edge Master Clocks are optimized to enable economic deployment of small cells and meet the stringent timing and synchronization requirements of 4G/LTE networks following the approach recommended in the ITU-T G.8275.2 standard for partial on-path support.

Edge Master Clocks

the continuing evolution of mobile network technologies has driven the need for increased accuracy and greater availability of timing and synchronization signals. At the same time, backhaul networks with high packet delay variation present timing "jitter variation" and asymmetry challenges that are difficult to solve with current solutions. Retrofit of backhaul networks for full on-path support is often not economically feasible, while deploying a GNSS receiver at every base station location is impractical, particularly in many small cell environments. Together, these issues create the need for a new synchronization distribution architecture for LTE networks. In frequency synchronized networks (LTE-FDD, as well as 2G/3G), Together, Microsemi's Edge Master products enable synchronization distribution solutions that allow the mobile network to continue to evolve without retrofit of existing backhaul equipment and without changes to current network design and switching/routing policies.

TimeProvider 2700 Edge Grandmaster Clock

The TimeProvider 2700 PTP Grandmaster standard capabilities include either a GPS or GLONASS input, allowing it to fulfill the requirements as a Primary Reference Time Clock as defined by the ITU-T G.8272 standard for phase and time synchronization, as well as G.811 for frequency reference. The TimeProvider 2700 provides two gigabit Ethernet interfaces in a combo port configuration supporting use of either copper or optical connections. Synchronous Ethernet is supported on the input and output ports. The PTP output capacity is standardized to 8 clients in basic models. This option includes Microsemi's unique Automatic Path Asymmetry Compensation feature providing increased accuracy and stability in the PTP timing signal. An option for E1/T1 input/output is also available.

Greater client capacity:

PTP client capacity in deployed units can be increased with a simple license key installation, allowing network engineers to design for the capacity they need today and be protected for increased requirements in the future

Concurrent GPS and GLONASS:

The base configuration allows the choice of either the GPS or the GLONASS GNSS system for the primary reference signal. A software license option enables support for both GPS and GLONASS concurrently, providing a greater level of sync network protection against GPS jamming alone.
