Peregrine Semiconductor and E2v Introduce Ultra-Low Phase Noise FRAC-N PLL For Commercial Space

[Via Satellite 09-14-2016] Peregrine Semiconductor and e2v have introduce 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 e2v and Peregrine signed a strategic reseller agreement in February. Built on Peregrine’s radiation-tolerant UltraCMOS technology, the PE97640 will be manufactured and qualified by e2v.

Designed for commercial applications and capable of performing in harsh space conditions for more than 10 years, the PE97640 is radiation tolerant and immune to Single-Event Latch-up (SEL), which can occur in space and cause severe damage. This PLL uses a low power consumption of 75 milliamperes 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, the PE97640 offers RF engineers high signal precision, solid frequency stability and boasts significant performance specifications with both 5/6 and 10/11 prescalers, according to the companies.
