Thunderbolt GPS Disciplined Clock
Precise GPS Clock for Wireless Infrastructure

The Thunderbolt™ GPS Disciplined Clock is Trimble's latest offering for GPS synchronization devices targeting the wireless infrastructure. This fourth-generation GPS clock combines an 8-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.

Key Features and Benefits
Ovenized quartz oscillator provides clean 10 MHz (1 PPS) signal that maximizes bandwidth
Combined GPS receiver and ovenized oscillator minimizes size and cost
High volume manufacturing provides reliable low-cost products
