Audio processor delivers USB interface Product News 1/17/2008 Post a comment BridgeCo has announced an expansion of its audio interface processor and firmware product line at the NAMM conference in Anaheim. The new DM1200E processor provides an USB interface, enabling the development of audio interface systems that use USB instead of FireWire.
Simulation of Proprietary Low Power Wireless Systems Design How-To 1/17/2008 Post a comment When developing a proprietary short-range device system, it is critical to ensure that the design meets local regulatory requirements as well as design parameters. By using a simulation tool, designers can save time and keep regulations in mind.
DIY vacuum tube Audio DesignLine Blog 1/16/2008 1 comment This video by an amateur radio operator visually steps through the process of manually making a triode vacuum tube.
RF DAC targets DOCSIS 3.0 Product News 1/16/2008 Post a comment Maxim claims the MAX5881 is the industry's first 12-bit, 4.3 GS/s RF DAC to directly synthesize four QAM channels in the cable downstream band.
Software Defined Radio: What Every RF Engineer Should Know Design How-To 1/14/2008 Post a comment Software defined radio (SDR) has been one of your popular search topics this year on RF DesignLine. Recently I had the opportunity to hear from some people who are very active in this market. I've collected some of the highlights of their remarks, and have also included some links below to some popular SDR items appearing on the site in 2007.
Power punch to the middle Design How-To 1/14/2008 Post a comment We can visualize the four levels of "digital power," as most designers do, as progressing from on/off control for basic power management to full digital control for advanced dc/dc power conversion.
So many sockets, so little certainty News & Analysis 1/14/2008 Post a comment For vendors of analog ICs, the challenge is the sheer number of market variables: There are many potential "sockets" to fill, user needs are highly fragmented, and ultimate performance is not necessarily the goal in many applications.
Power amplifier boosts audio in automobiles Product News 1/9/2008 Post a comment Toshiba has designed its latest automotive IC, the TB2932HQ audio amplifier, with a new single-stage driver circuit structure that improves performance compared to its previous generation products based on BiCMOS technology for better sound.
Audio power amplifier adds 100-W per channel capability Product News 1/9/2008 Post a comment ST's STA510F PWM digital audio power amplifier adds 100-W per channel capability to its full flexible amplification (FFX) family. It also matches all PWM modulation schemes and eliminates the need for external control of power-supply turn-off sequence.
1080/60p HD encoder targets broadcast sector Product News 1/9/2008 Post a comment Horizon Semiconductors announced the immediate availability of a multi-standard native 1080/60p professional encoder IC for the cable, satellite, telco, terrestrial and mobile triple/quad-play broadcast markets.
DisplayPort ready to ramp in PCs, monitors News & Analysis 1/9/2008 Post a comment DisplayPort backers projected a complete picture of an interconnect standard ready to ramp at the Consumer Electronics Show, showing working chips and systems from multiple companies and a road map into the next year, indicating the specification has crossed the chasm from idea to product.
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.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
