Precision timing components manufacturer SiTime has introduced the Elite 2 Super-TCXO, a high-precision temperature-compensated oscillator, targeting improved GPU utilization in AI data centers. The device is designed to keep systems tightly synchronized. It delivers 1 ns time synchronization accuracy (up to 100× better), which keeps multiple GPUs operating in step. This reduces idle time between processors and improves overall compute efficiency in large AI workloads.
The oscillator maintains stable timing under changing conditions, with ±2 ppb/°C frequency temperature slope (dF/dT) and ±50 ppb frequency stability from -40°C to 105°C. It also achieves 6 × 10?¹² Allan Deviation (ADEV), meaning very low short-term timing variation. This keeps the system clock steady over time and temperature, preventing small timing errors from building up during long AI processing tasks.
“AI networks must operate with extremely high efficiency to fully utilize expensive GPU resources,” said Sameh Boujelbene, vice president at Dell’Oro Group. “As AI back-end infrastructure refreshes at a much faster cadence than traditional non-accelerated infrastructure, time synchronization accuracy becomes increasingly important to sustaining performance across rapidly evolving data center architectures.”
Built on silicon MEMS technology (microelectromechanical systems), the oscillator avoids activity dips and micro-jumps seen in quartz devices. It is resistant to shock, vibration, and board bending, improving reliability in dense server environments.
The Elite 2 Super-TCXO comes in a compact 3.2 mm × 2.5 mm (8 mm²) footprint, with an option for a 5.0 mm × 3.2 mm package, helping reduce board space. It also supports digital frequency tuning, making it easier to align timing across complex systems. The product is currently sampling, with production expected in Q3 2026.
