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 GPS clock’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 wireless local loop .

The architecture is comparable to systems currently used to maintain the tough CDMA holdover specification.
This makes the Thunderbolt E GPS clock a natural for a CDMA clock, the digital standard for cellular phones.

The Thunderbolt E GPS clock outputs a 10 MHz reference signal and a 1 PPS signal with an over-determined solution synchronized to GPS or UTC time. The 10 MHz reference accommodates applications requiring sub-microsecond timing.

The Trimble T-RAIM (Time-Receiver Autonomous Integrity Monitor) algorithm is used to monitor satellites to ensure signal integrity.

Matching the Thunderbolt E GPS Clock with the Trimble Bullet™ antenna creates a system that provides reliable performance in hostile R/F environments. The system can be easily calibrated for different cable lengths.

The high level of integration and volume production techniques make the Thunderbolt E GPS Disciplined Clock an extremely cost-competitive timing solution for volume synchronization applications.

Main Differences between Red Thunderbolt 48050- 61 and Thunderbolt E 60333- 30

The Thunderbolt E now has 12 channels, is RoHS compliant,
