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.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
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.
