By Chris Francis I have used various programmable clock generator chips, such as the PLL based devices from IDT for generating high frequency clocks in mixed signal systems, such as pixel clocks for analog to digital converters in video systems. In those applications precision frequencies can be important and speed can be more than 100MHz. […]

AD9850 Direct Digital Synthesis Chip: How is it used?
By Chris Francis There are a number of DDS chips around. Taking Analog Devices as an example, they range from simple, low speed, low cost devices such as the AD9837 (5MHz or 16MHz clock) for around $2 to the AD9914 3.5Gs/s costing over $180. Some are aimed at function generators, some for test and measurement, […]
Xilinx and TSMC Reach Volume Production on all 28nm CoWoS™
Xilinx, Inc. (NASDAQ: XLNX) and TSMC (TWSE: 2330, NYSE: TSM) announced production release of the Virtex®-7 HT family, the industry’s first heterogeneous 3D ICs in production. With this milestone, all Xilinx 28nm 3D IC families are now in volume production. These 28nm devices were developed on TSMC’s Chip-on-Wafer-on-Substrate (CoWoS™) 3D IC process that produces significant […]

Texas Instruments Names Winner of TI Analog Design Contest
Texas Instruments awarded Adam Munich, a freshman from Rochester Institute of Technology, as the overall winner of the Engibous Prize in its sixth annual TI Analog Design Contest. This contest showcases the innovative projects and competitive spirit of today’s future engineers. Munich’s project focused on improving the original Tesla coil, which is used to produce high-voltage, low-current […]
1-Wire Thermocouple-to-Digital Converters
The MAX31850/MAX31851, cold-junction-compensated, 1-Wire thermocouple-to-digital converters were introduced today. The devices achieve ±2.0°C accuracy (not including sensor nonlinearity) while integrating all of the functions required for a complete (thermocouple-to-digital solution). Additionally, the MAX31850/MAX31851’s 1-Wire interface allows multiple sensor locations to communicate and draw power over a single data line, greatly simplifying wiring requirements. Designers can […]
MEMS Wireless Vibration Sensing System
The wireless vibration sensing system allows industrial systems operators to remotely monitor production equipment health, improve system performance, and reduce maintenance costs. The new networked system includes the ADIS16229 iSensor wireless vibration sensor node, which combines dual-axis digital MEMs (micro-electro mechanical systems) acceleration sensing with advanced frequency-domain and time-domain signal processing. The sensing system […]
