Vectron International announces the VC-826 differential XO in a 3225 (3.2 x 2.5 mm) package. The VC-826 XO is designed to support applications that require low jitter (under 200 fsec) at standard frequencies from 20 to 170 MHz. Vectron's VC–826 is designed for use with PHY/SERDES, high speed converters, ASICs and FPGAs in communications platforms, medical and industrial markets.
Astronomers using the new Atacama Large Millimeter/submillimeter Array (ALMA) have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust trap has been clearly observed and modelled. It solves a long-standing mystery about how dust particles in discs grow to larger sizes so that they can eventually form comets, planets and other rocky bodies. The results are published in the journal Science on 7 June 2013.
