Our Technology

Solving The Phase Noise Challenge

The accuracy and frequency requirements of clocks are increasing rapidly as networks are upgrading to meet exploding bandwidth requirements.  The phase noise (or spectral purity) of the clocks is becoming a fundamental source of performance degradation in 5G mm-wave communication systems and in automotive and defense radar systems. 

Crystals provide excellent phase noise and stability at a single fixed low frequency. 

SAW devices provide excellent phase noise at fixed multi-GHz frequencies but with poorer stability. 

Phase Locked Loops (PLLs) provide higher multi-GHz frequencies with good stability and programmability but at the expense of  degraded phase noise.

The Virtual Crystal is the only technology in the world that simultaneously provides the low phase noise of a SAW, the superior stability of a crystal and the fine programmability of a PLL  at multi-GHz frequencies.
