Isola Group S.a.r.l. announced its new low loss, low skew, high-speed material, GigaSync (tm). This product has been engineered to eliminate skew issues in high-speed designs that use differential pairs to create a balanced transmission system able to carry differential (equal and opposite) signals across a printed circuit board. The company will immediately begin alpha site testing of GigaSync and expects field validation using industry-standard Test Vehicles (TVs) to be completed by November 2013.
Much has been written about jitter and skew on gigabit per second and faster differential signals that are traceable to the glass weave in PCB laminates. Skew caused by the fiber weave effect can be as high as 130 picoseconds when trace lengths exceed 20 inches. Speeding Edge, a consulting firm supporting several manufacturers of ultra-high performance products, has successfully validated that GigaSync reduces weave-induced skew on high-speed designs from 25 Gb/s on up to 100 Gb/s, using its proprietary Signal Integrity (SI) TV.
Lee Ritchey, President of Speeding Edge, stated, "This material demonstrated the lowest skew that we have ever tested without relying on off-angle routing or off-angle fabrication. GigaSync makes designing very high-speed differential pairs as easy as its low-speed counterparts."
