Microsemi's Edge 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. Microsemi's TimeProvider ® 2700 Edge Grandmaster Clock and TimeProvider ® 2300 Edge Boundary Clock are 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.
TimeProvider 2300 Edge Boundary Clock
The TimeProvider 2300 PTP Boundary Clock provides two gigabit Ethernet interfaces in a combo port configuration supporting use of either copper or optical connections. They are configured as one PTP input port and one PTP output port. Synchronous Ethernet is supported on both ports. Models are available to support up to 512 PTP clients; all operating at the full 128 messages per second rate. Client capacity can be increased in the field with software license options. The TimeProvider 2300 is available with either an OCXO or rubidium oscillator; each delivering a different level of phase and frequency holdover performance and allowing operators to better optimize their network SLAs. The TimeProvider 2300 includes a programmable 10 MHz or 1 PPS BNC port and a PPS+TOD RS422 on an RJ45 connection. Models with either dual DC or a single AC power input are available. An option for E1/T1 input/output is also available
Sync solution for the mobile network edge: 4G/LTE and small cells
No change out or upgrade of network hardware
Mitigates impact of backhaul noise, packet delay variation, and load asymmetry
Synchronization protection for high network availability
Preserves current MPLS network engineering
As tighter synchronization becomes more essential to the normal operation of the network (Inter-Cell Interference Coordination, for example) the negative impact of losing synchronization becomes more significant. Rubidium oscillators provide a way to protect synchronization by delivering best-in-class holdover performance (phase timing of ±1.5 µsec for up to 24 hours). Often seen as expensive upgrades for individual macro base stations, rubidium oscillators in an advanced gateway clock are now more affordable as their cost is amortized across an entire cluster of small cells and co-located macro base stations.
