Disciplined Clocks – NTP | PTP | 1 PPS

Disciplined Clocks are a trusted and accurate source of timing. Even when GNSS signals are unavailable, they continue to output precise time. These powerful devices consist of GNSS receivers that discipline high quality oscillators to provide a highly accurate time source, comparable to expensive atomic frequency standards. Protempis disciplined clock product lines offer a range of performance choices holdover, phase noise, size and cost, ideally suitable for your application.

Thunderbolt® E GPS Disciplined Clock

The Trimble® Thunderbolt® E GPS Disciplined Clock is Trimble’s latest offering for GPS synchronization devices targeting the wireless infrastructure. This fifth-generation GPS clock combines a 12-channel GPS receiver, control circuitry, and a high-quality ovenized oscillator on a single board, providing increased integrity and reliability at a lower size and cost.

The Thunderbolt E’s level of integration makes it a perfect solution for precise timing applications in the wireless industry. Among its uses are synchronizing the E911 positioning infrastructure and maximizing bandwidth for a wireless local loop. The architecture is comparable to systems currently used to maintain CDMA holdover performance requirements in telecommunications systems.


High volume manufacturing provides reliable low-cost products

Small form-factor idea in its case or as a board only can be embedded into digital broadcast applications as a cost-effective frequency source

Provides reliable performance in hostile RF environments

Extremely cost-competitive timing solution for volume synchronization applications due to a high level of integration and volume production techniques
