[{"type":"text","content":"\nEndura Super-TCXO Delivers Superior Holdover and Ruggedized Performance for Aerospace, Defense and Industrial Applications\n\n SANTA CLARA, Calif.--(BUSINESS WIRE)--\nSiTime Corporation (NASDAQ: SITM), the Precision Timing company, today launched the Endura® temperature compensated oscillator (Super-TCXO®), ENDR-TTT, for position, navigation and timing (PNT) applications. Engineered for superior holdover – uninterrupted operation when GNSS is not available – and resistance to jamming and spoofing, ENDR-TTT is an ultra-stable, low-power product for GNSS receivers in aerospace, defense, and industrial markets.\nThis press release features multimedia.

The second layer addresses exceptionally large search windows, such as in first acquisition, where spoofers can be tracked. In this case, the spoofer signals can be identified and removed due to SiTime’s ultra-stable reference clock.”\n\nWhen GNSS signals are dropped due to unavailability or degradation—including signal jamming or extreme environmental conditions—holdover maintains timing stability locally to enable uninterrupted network operation. The ENDR-TTT Endura Super-TCXO provides up to 20x longer holdover and 20x better PNT accuracy, dramatically improving spoofing resistance.\n\n“SiTime’s ENDR-TTT Endura Super-TCXO accelerates GNSS recovery by narrowing the resynchronization window, reducing spoofing and setting a new standard for ruggedized Precision Timing,” said Piyush Sevalia, executive vice president of marketing at SiTime. “Our latest product delivers a powerful combination of superior performance, low power, and small size, that leads the industry for PNT applications.”\n\nAdditional features for SiTime ENDR-TTT Endura Super-TCXO include:\n\n\n±50 ppb stability over t...
