10     Trimble ThunderBolt E GPS Disciplined Clock User Guide

The ThunderBolt E GPS disciplined clock provides time and frequency through a 
12-channel GPS receiver and a high-quality ovenized quartz oscillator integrated onto 
a single printed circuit board. Tightly integrating GPS into the clock design eliminates 
the need for a separate GPS receiver. This results in better reliability, a smaller size, and 
a cost advantage.

The board in the ThunderBolt E consists of one board with GPS and a 24 V power 
supply regulator. This power supply regulator ensures clean, robust power to the GPS. 
The board can support several different oscillators for applications having stringent 
holdover requirements.

The ThunderBolt E is ready to use out of the box for most applications. When a 
+24 VDC power source is applied, the ThunderBolt E will begin to track satellites—
four satellites are required to begin the self-survey process. At the same time the 
oscillator will come up to operating temperature and stabilize, outputting the 1 PPS 
and reference frequency.

To get the most from your time reference, you can customize the ThunderBolt E using 
the Trimble binary interface, TSIP (Trimble Standard Interface Protocol). For more

The ThunderBolt E uses the Trimble Standard Interface Protocol (TSIP). This is a 
binary packet protocol that allows the system designer maximum configuration 
control over the GPS receiver for optimum performance in timing applications. TSIP
