250-Msample/s 16-Bit ADCs Incorporate Fast JESD204B Interface

With the release of JEDEC’s JESD204B serial data interface, designers are abandoning the 14- to 16-bit parallel differential low-voltage differential signaling (LVDS) connections from analog-to-digital converters (ADCs) to FPGAs, DSPs, or some ASICs. This reduces the number of lines and lengthens the runs for a simpler circuit. Recently, Texas Instruments adopted the JESD204B interface for its 16-bit ADS42JB69 ADC. The …

Creating a Miniaturized Analog Controlled Servo

Contributed by Solutions Cubed, LLC 3/21/2012 Position control on a small scale Advanced position control systems have been used in industrial control applications for decades. Often these systems are complex and expensive, as well as necessary. In today’s electronic marketplace options exist that allow for very small and inexpensive position control systems. It is now possible to affordably provide advanced …

Improve Your Jitter Performance In Communications Systems

In digital, analog, and RF communications systems, jitter plays a large role in the degradation of signal integrity. This can include a reduced signal-to-noise ratio (SNR) or effective number of bits (ENOB) in analog-to-digital converters (ADCs) or increased bit error rate (BER) in digital and optical channels. Once you examine its sources, you can improve jitter performance from a systems …

What’s Inside Your RF Signal Analyzer?

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often requires understanding what’s inside-mixers, filters, oscillators, amplifiers, and more-and how it all works together to make up an RF signal analyzer (or receiver, for that matter). Mixers Those …

Latest Micro Dev Kits Make For Too Many Toys, Too Little Time

Intel’s original 8-bit 8008 came in an 18-pin dual inline package (DIP), and it was the hot tech item when I was an electrical engineering student back at Georgia Tech. It only had a 14-bit address bus and would have gone nicely with the SRAM and EPROMs that I had on hand. The 8008 was made available to students …
