ELECTRONICS: Crystek’s CPLL58-3900-4300 PLL/Synthesizer operates from 3,900 to 4,300 MHz with a typical step size of 2,500 KHz. Engineered and manufactured in the U.S., it is housed in a compact 0.582 x 0.8 x 0.15-inch SMD package, which saves board space. Crystek’s PLL/Synthesizer construction essentially wraps a VCO around a PLL in a package that’s only marginally larger than a VCO on its own, and significantly smaller than separate VCO/PLL modules. The CPLL58-3900-4300 needs only an external frequency reference and supply voltages for the internal PLL (phase lock loop) and VCO (voltage controlled oscillator), and is programmed using a standard three line interface (Data, Clock and Load Enable). Typical phase noise for the CPLL58-3900-4300 is -95 dBc/Hz at 10 KHz offset with minimum output power of 3 dBm. VCO voltage is 5V dc; PLL voltage is 3V dc. Second harmonic suppression is -15 dBc typical. It is ideal for use in telecommunications, computers, radio equipment, base stations and other electronic applications.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
