Announced high-precision TCXO "SiT5543" that can be used for aerospace and defense applications

The SiT5543 is a TCXO (Temperature Compensated Oscillator) that achieves ±5ppb (±0.005ppm).

It is a product that can completely fulfill the role of conventional OCXOs (Oven Oven Oscillators), which have been used as high-precision clock sources for systems.

Like SiTime's previous products, it is a MEMS oscillator, so it is extremely reliable compared to crystal oscillators.
