The Protempis Thunderbolt® PTP Grandmaster Clock is designed for Public & Private Wireless, Data and Industrial networks that require timing & phase synchronisation.
The GM200 employs Protempis’ GNSS solution & Holdover technology and can tolerate harsh environmental conditions supporting both indoor & outdoor deployments with extended industrial operating temperature range.
Key Features
• IEEE-1588 PTP Grandmaster Clock
• Multiple PTP Profiles
• Multi-Constellation (GPS, GLONASS, Beidou, Galileo and QZSS)
• 15ns (1-sigma) time accuracy relative to GNSS reference
• Holdover of ±1.5us over 4 hours
• ITU-T G.8272 PRTC
• Inputs: GNSS, 1588-PTP, and SyncE
• Outputs: 1588-PTP, NTP, SyncE, PPS, and 10MHz
The GM200 is designed with small cells in mind but also meets the macro base station requirements for synchronisation. The Thunderbolt supports small cell networks that require phase synchronisation. The most efficient way to implement phase synchronisation for LTE & LTE-A /5G services is to deploy the grandmaster clock close to the target eNodeB to provide 1.5 us of phase alignment. By reducing network hops between the grandmaster and LTE base stations, the risk of network re-configuration, and load variance on IEEE-1588 signal quality is reduced. The GM200 suits this strategy perfectly due to its small size, low cost, superior accuracy & reliability, and flexibility of deployment options.
LTE-A & 5G Services
By engineering current networks to support phase synchronisation, LTE-A/5G services downtime can be mitigated. Phase
synchronisation can easily be supported by adding the GM200 to current sync networks where needed. Given its low cost, it can be added to any network requiring support for the stringent phase synchronisation specifications that LTE-A/5G services. High reliability assures that the GM200 can be deployed in edge and/or aggregation networks.
ORAN 5G
More Telcos are adopting the Open RAN architecture, this allows timing technologies like the Protempis’ GM200 to be used in the 5G infrastructure The GM220 can function as a PTP Grand Master distributing precise timing over a packet-based network.
Private 5G & Industrial Data Networks
With the introduction of CBRS, private Industrial Data networks, third-party providers and municipalities are building their own networks. Private 5G allows an alternative to WI-FI. The benefit is better range and coverage when compared to WI-FI. Having Protempis’ proven timing technologies on your side helps make private cellular networks a viable option.
