Ultra-Low Phase Noise PLL for Commercial Space Applications

e2v and Peregrine Semiconductor have introduced the PE97640, an ultra-low phase noise FRAC-N phase-locked loop (PLL) for commercial space applications. Available exclusively through e2v, the PE97640 is the first new space product since they signed a strategic reseller agreement in February. Built on Peregrine’s radiation-tolerant UltraCMOS® technology, it will be manufactured and qualified by e2v.

By aligning the strengths of both organizations, they plan to accelerate new product introductions for UltraCMOS high-reliability space products, like the PE97640. Designed for commercial applications and capable of performing in harsh space conditions for over ten years, the PE97640 is radiation tolerant and immune to single-event latch-up (SEL), which can occur in space and cause severe damage. This low power PLL consumes 75 mA of current at 2.7V, enabling RF system engineers to better allocate power resources.

The PE97640 has a FRAC-N frequency synthesizer that generates multiple output frequencies from a single reference input frequency. The divided-down output then enables reference and phase detection at a lower frequency, handling both frequency and phase lock. With superior phase noise performance, it offers RF engineers high signal precision, solid frequency stability and boasts significant performance specifications with both 5/6 and 10/11 prescalers:

Manufacturing the PE97640 on behalf of Peregrine also allows e2v to offer an even broader range of signal-processing solutions to the space market.
