Trimble HK Thunderbolt PTP GM200

Thunderbolt® PTP Grandmaster Clock GM200

The Trimble Thunderbolt® PTP Grandmaster Clock is designed for wireless networks requiring phase synchronization. The GM200 provides continuous availability of UTC traceable time for phase synchronization, a must for LTE-Advanced networks and services.

The Thunderbolt PTP GM200 employs industry leading Trimble GNSS solution & holdover technology.

The PTP GM200 can tolerate harsh environmental conditions supporting both indoors & outdoors deployments with extended operating temperature range.

Key Features:

  • IEEE-1588 PTP Grandmaster Clock

    • Multiple PTP Profiles(G.8265.1, G.8275.1, G.8275.2,Telecom-2008 Profile)

    • Supports 64 PTP clients @ 128pkt/s

  • Multi-Constellation (GPS, GLONASS, Beidou & Galileo)

  • 15ns (1-sigma) time accuracy relative to GNSS reference

  • Holdover of ±1.5us over 4hours (constant temperature and when locked to GPS for 7 days)

  • Inputs: GNSS, 1588-PTP and SyncE

  • Outputs: 1588-PTP, NTP, SyncE, PPS,and 10MHz

  • Dedicated management port (1xRJ45)

  • Network Management: SNMP, Web UI, CLI

  • VLAN support

  • IPv4 and IPv6


  • Low cost reduces CAPEX of LTE TDD, LTE-A & small cell projects

  • Extended environmental capabilities enable deployment in difficult locations where small cells and

        LTE-A base stations are deployed Superior hold over performance via Trimble proprietary

        technology gives extra time error budget for network design and dimensioning.
