X-EMI, a fabless semiconductor company focused on electromagnetic interference reduction, introduced its XM1001 transceiver at EMC 2005, a trade show held in Chicago, Illinois. The new transceiver is the first of several that X-EMI has planned intended to reduce electromagnetic interference in electronic systems. The demonstration at the show illustrates how the XM1001 reduces EMI 25 dB without added shielding, without design changes and with no added jitter.

The XM1001, which is reported as in the sampling stage, is a clock generator / clock transceiver chip, which according to the company can reduce EMI radiation levels over 25 dB based on what the company calls Optimized Spectral Diffusion (OSD).  Larry Woodson, CEO of X-EMI, indicated that the 25 dB number is conservative, "We tested the XM1001 both internally, and externally in an independent lab environment, where the results were actually greater than 25 dB of EMI reduction. However, we know that real life does not often imitate a lab environment, no matter how careful we are to replicate it. We also know that our best endorsements come from outside experts and our customers who are currently sampling the product. We feel comfortable in saying that designers and developers of electronics systems will not approach EMI reduction in the same way again, and product marketers will no longer fear a time-to-market delay due to emission compliance. This small chip could save a multi-million dollar product launch, and spread across several electronics industries, that translates into billions of dollars saved."

Dr. Howard Johnson, who is considered an EMI industry expert, (http://www.sigcon.com/), was very positive about X-EMI’s new chip, "I have often fantasized about clock transceiver technology that combines zero jitter and zero emissions. Today, X-EMI brought my dream one step closer to reality. OSD integrates the best aspects of spread spectrum modulation with reliable digital system design practice. The XM1001 produces clock signals that are full-sized, with great signal quality, and low jitter, but the radiation simply vanishes. If radiation from your clock was a problem before, it isn't a problem any more. "

The XM1001 is also classified as a stand-alone oscillator and / or frequency synthesizer that offers both differential or single-ended input and output, in addition to supporting PCI Express and SATA applications. The chip’s specifications permit operation up to 250 MHz, a cycle to cycle jitter of less than 25 picoseconds, and a plus or minus 300 parts per million clock output frequency accuracy

With the product announcement, X-EMI also said that it has achieved its product and funding goals for 2005, noting that it raised $13 million in a Series A round in July.  As far as its marketing efforts, the company reported that it has entered into agreement with Magellan Discovery and Nova Marketing in regards to the marketing and distribution of their product in the Pan Asian and United States market, respectively.
