Engineered for the world’s toughest applications
Timing devices provide the heartbeat in mission-critical electronic equipment. These devices must reliably operate in the harshest environments.
If timing fails…
- Receivers lose lock to satellites
- Navigation systems can receive the wrong coordinates
- The mission can be compromised
Our ruggedized Endura™ MEMS timing solutions, with up to 50 times better acceleration sensitivity, provide the robustness and reliability needed to operate in the most rugged conditions. Endura products conform to MIL-PRF-55310 specifications and can be up-screened in accordance with standard or custom flows.
