Random or Deterministic: Understanding jitter is key to serial data comm success

8/27/2003   Post a comment
With serial data communications clocking faster, tutorials on jitter become like garlic in cooking: It is impossible to do too much. This article, from Agilent Technologies " a company that knows something about the subject " introduces jitter, and the ways it can be measured. Though jitter shows up in a wide variety of diverse applications " ranging from oscillator design to telecommunication network synchronization " engineers Johnnie Hancock and Steven Draving focus primarily on serial data c

Our friend Raminderpal has been our "go-to-guy" on signal integrity issues, pertaining to both mixed-signal ICs and boards. A senior engineering manager at IBM Microelectronics, a frequent contributor to EE Times, and author of a John Wiley & Sons text on signal integrity, Singh is spokesperson for the Virtual Socket Initiative Association. This column was put together in response to a Planet Analog poll.
Whither analog EDA?

If there's such a demand for analog IP, Steve Ohr wonders in this expanded version of a PA magazine editorial, why are the analog EDA startups (and IP providers) having such a rough time? Why did analog methodology/tools/IP vendor Antrim Design Systems rollover and die? Why did BTA become Celestry become Cadence? Why is NeoLinear too within Cadence's gravitational pull? Why is the business fate of Barcelona Design such a mystery? Are analog enthusiasts like Cadence founder Jim Solomon, refusing

Signals passing through the air are distorted by atmospheric and environmental impairments including multipath scattering and dispersion, writes Noah Schmidtz in this much expanded version of his contribution to EE Times' InFocus section on RF test. "As a cell phone user, you know that dropping a call in the middle of a conversation is annoying, if not dangerous in emergency situations," Schmidtz says. "As a wireless device designer, it is imperative to verify receiver performance in real-world
Power to the People: Digitally-Controlled Power (DCP) moves into mobile phones

The proliferation of features in new mobile phones has outstripped the capabilities of today's integrated analog power management ICs, driving up component counts and lengthening development times. However, the answer to this problem is emerging in the form of Digitally-Controlled Power (DCP), which not only can achieve significant component count reduction, but also can cut handset development time dramatically, according to iSuppli Corp.

There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
