    Understanding radiation reports: the low down on particle LET

    There are high levels of radiation in space, primarily electrons, protons and heavier ions. When an energetic particle travels through matter (like silicon), it suffers numerous interactions that extract some of its kinetic energy. The energy lost ...

    Can a clock generator act as a jitter cleaner?

    I’m excited to have the opportunity to address clock generators and jitter cleaners. My goal is that after reading this post, you will not stereotype a clock generator as a device that can’t also perform jitter cleaning. I will discuss the difference between clock generators and jitter cleaners, cover some key points about phase-locked loops...

    Professional audio equipment made the most noise at the 2017 NAMM Show

    Guitars, drums, cymbals … the 2017 National Association of Music Merchants (NAMM) Show had it all, but what seemed to be making the most noise was the professional audio gear. I’ve heard a lot about the NAMM Show, the largest music gear conference in the U.S. (probably the world), and my excitement attending for the first time was hard...

    What are the building blocks of Bluetooth speakers?

    Bluetooth® speakers are now fairly common in the marketplace. Many manufacturers offer very basic systems selling for a few dollars to high-end systems selling for hundreds, with varying degrees of audio performance. The Bluetooth market is highl...

    Digital signal processing in RF sampling DACs

    In this blog post, I will discuss the important digital signal processing (DSP) blocks that create all of the magic in direct RF sampling DACs. These blocks include interpolation filters, mixers, numerically controlled oscillators (NCOs), summers and inverse sinc filters. What makes RF sampling devices magical is that they combine digital interpolation...

    RF sampling: Learning more about Latency

    In this post, I’m going to discuss latency in an analog-to-digital converter (ADC). Latency is the time it takes for a signal to travel from point A to point B. In an ADC, latency is how long it takes from the time that an analog input is applied to the time that the digital output word becomes available. Why is latency important? Regardless...

    Solve the challenge of too many wires in high-speed networking equipment

    Top-of-rack (ToR) switches, routers, servers and storage, types of today’s high-speed communications equipment , are among the most sleek, powerful and meticulously designed workhorses of the data center. They contain impressive circuitry, pushing +25Gbps with scores of ports, complex switch application-specific integrated circuits (ASICs) and...

    Inductive sensing: reliably detect faults in circuit breakers using contactless inductive switches

    In my last blog post , I discussed how to use inductive switches for proximity applications. In this post, I want to discuss how to use inductive switches in slide switch applications to make circuit breakers more reliable. Circuit breakers typically ...

    Explore the non-speed-related benefits of CAN FD

    Most discussions about Controller Area Network with Flexible Data-Rate (CAN FD) invariably revolve around its most distinctive feature – increased speed. Naturally, this leads to the assumption that if you don’t need the speed, then you don’t need FD. But that is not always true! Join me as I take a look at a couple of the lesser-known...

    Don’t let bad reference signals destroy the phase noise in your PLL/synthesizer

    “You are what you eat” is a commonly heard saying that recommends the careful selection of food, given its ability to directly affect our health and well-being. Although not an exact comparison, the concept applies if you think of your input reference signal as the food, ingested by the phase-locked loop (PLL)/synthesizer, which affects...
