Metcalfe on Ethernet’s lessons, unsung heros Blog 11/29/2012 6 comments “There’s an army of unsung engineers who helped invent Ethernet,” says Bob Metcalfe, taking a long drag on his cigarette as he ruminates about the now ubiquitous network technology he described in a memo to colleagues at Xerox PARC on May 22, 1973.
You too can be a "Layaway Santa" Programmable Logic DesignLine Blog 11/28/2012 Post a comment I think this is a jolly good idea, and that any of us with a few extra dollars in our pockets should think seriously about spreading a little cheer.

Freescale's i.MX 7 canned as firm refocuses The Engineering Life - Around the Web 11/21/2012 5 comments The mobile and tablet market can be a money maker for some and a deal breaker for others. For Freescale, it seems to be the latter, with the firm choosing to discontinue its high end i.MX 7 mobile processor line, in favor of lower powered chips aimed more at the internet of things.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
