The World’s First instantaneous Loop (iL)

ideal clocking and instantaneous wireless

ABOUT US

Traditional Phase Locked Loops (PLL) have notoriously been forced to compromise their performance far from ideal, via increased loop filtering. This inherent limitation severely degrades phase coherence in order to maintain loop stability. Gain ICs has eliminated this, achieving exact phase coherence, or ideal phase tracking across the widest possible tracking bandwidth, while increasing loop stability to realize ideal PLLs.

These instantaneous loops (iL) reduce jitter by greater than 10 times in clocking applications, cancelling jitter peaking and greatly attenuating jitter accumulation, and enable breakthrough advances in communications. Ideal phase coherence now allows for tracking extremely fast modulation, increasing bitrates to ½ that of carrier frequencies. In contrast, 5G wireless communication requires a 28 GHz carrier to attain 1.5 Gb/s throughput, or 1/20th carrier to bitrate ratio. This 10 times higher ratio degrades performance by decreasing range by 100 times in 5G from free space loss alone. In serial links line resistance decreases by a factor of 10 using iL for modulation, due to increased skin depth from much lower frequencies, effectively forcing current solutions into much lower bitrates.

Utilizing iL, instantaneous wireless (iW) achieves other large advances relative to 5G. Eliminating down conversion reduces channel noise by more than half. Decreasing constellation size to 2 versus the 256 QAM needs to achieve the same high bitrates increases signal space by orders of magnitude. Together these translate into 107 less average bit energy required to achieve the same reliability while increasing range to more than 140 times, including the increase from lower free space loss. Less average bit energy to achieve greater performance also translates in greater spectral efficiencies. With 140 times fewer cell towers to cover a linear route, iW would reduce costs to roughly 1% those of 5G, while achieving far greater performance.
