PCB Piezotronics : MEMS accelerometers measure high-g shock events Product News 6/24/2009 Post a comment PCB series 3991/3501 MEMS shock accelerometers represent state-of-the-art technology for miniature, high-amplitude, dc response acceleration sensors, capable of measuring long duration transient motion, as well as responding to and surviving extremely fast rise times typical of high-g shock events.
Beyond-IR: Remote Controls for Home Entertainment Design How-To 6/17/2009 3 comments The alternative to infrared remote control technologies is RF-based remote controls. RF-based remote controls overcome three major limitations of infrared technologies: line-of-sight and range; one-way communications; and high power consumption. Let's take a look at each of these limitations.
The Art of Ambient Light Sensing Design How-To 6/10/2009 Post a comment The ability for a display to sense ambient light could be a powerful tool that can lead to increased power efficiency and customer satisfaction. This application note will discuss some of the benefits of implementing ambient light sensing as well as some considerations to keep in mind during the design.
Epcos rolls rugged inductors for automotive use Product News 6/10/2009 Post a comment Epcos AG presents an improved and particularly rugged version of SMT power inductors for automotive electronics. Their design, which features a baseplate with injection-molded termination clips, increases the mechanical stability and improves the temperature distribution during the solder process. Lands with a nickel barrier-layer coating satisfy the tougher demands for use in automotive electronics.
MEMS oscillators available for industrial temperature ranges Product News 6/8/2009 Post a comment MEMS oscillator's instability at extreme temperatures has been one of the reasons that crystal oscillators still have a foothold in many industrial applications. That might change now that Discera has expanded its PureSilicon product offering to include industrial temperature ranges.
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.
