    How to select a redriver or retimer for HDMI 2.0 jitter cleansing

    Signal integrity has always been a priority for high-speed signal interfaces like High-Definition Multimedia Interface (HDMI), which runs at 6Gbps. As the HDMI 2.0 signal travels from a graphics processing unit (GPU), central processing unit (CPU) or Platform Controller Hub (PCH) to an end receiver such as a TV or monitor, several factors can cause...

    Three reasons why a bidirectional I/O will simplify your next 4K video design

    As 4K video becomes the norm for the professional video industry, high-quality serial digital interface (SDI) components and meticulous board layout are imperative for a high-performance end product. In addition, flexibility, scalability and cost savings are necessary to maximize design reuse, whether you are looking to expand your 12G product portfolio...

    Digital signal processing in RF sampling DACs – part 2

    In this blog post, I will describe mixers and numerically controlled oscillators (NCOs), which are the basic building blocks used to implement digital up converters (DUCs) in the RF sampling digital-to-analog converter (DAC) signal chain. In the previous installment of this series, I explained the use of interpolation filters to increase the data...

    RS-232: Use this old dog for new tricks

    The other day, as my dad was guiding me on a tour of his metal manufacturing shop, we stopped at a computer numerical control (CNC) machine, like that seen in Figure 1 that’s just about as old as I am. After unscrewing a latch, he revealed none...

    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...
