Movandi unveils 75 fs clock synthesizers at 150 mW

In a wireless or AI system, a clock is the invisible metronome keeping data moving in step. Movandi has introduced two frequency synthesizers, the MV3564 and MV3514, that the company says deliver 75 fs total jitter at 150 mW. The devices were due for demonstration at LEAP 2026 in Riyadh, Saudi Arabia, from August 31–September 3.

The chips are built on TSMC’s 40nm radio-frequency CMOS process and combine a voltage-controlled oscillator, or VCO, with multi-PLL frequency and phase synchronization. Functions that would otherwise require separate components are integrated into the synthesizer, an architecture Movandi says can reduce component count, footprint and system complexity. An integrated alignment engine provides deterministic phase re-synchronization and 30-bit fine phase adjustment.

The two devices share the same pins and features but cover different frequency bands. The MV3564 supports 4.3–8.7 GHz and 8.6–12.3 GHz; the MV3514 supports 7.76–9.84 GHz and 12.33–14.34 GHz. Together, they are designed for clock requirements ranging from 4 GHz to THz frequencies, with support for an internal crystal or an external reference clock.

And so what, concretely? Designers working on 5G and emerging 6G infrastructure, AI links inside and between data-center networks, high-speed analog-to-digital and digital-to-analog converters, or power-constrained robots, drones and intelligent edge devices could use the same device architecture across different configurations. If Movandi’s comparison holds in system testing, the claimed 150 mW draw could ease power and space pressure in those designs.

The limit is clear: the figures and the 10× comparison come from Movandi, and the available report does not include an independent measurement or a field deployment. For now, the company has introduced the components and presented their intended applications; the next test is whether the promised integration and power savings carry into real wireless and AI hardware.
