Every oscillator has at least one active device.This active device acts as an amplifier.There are many types of oscillator devices, but they all

Modulating a sine-wave carrier makes it possible to keep the frequency content of the transferred signal as close as possible to the centre frequency

Any radio frequency feedback oscillator topology can be operated as a regenerative receiver if modified to provide a controllable reduction in

CONGLETON, England--(BUSINESS WIRE)--eoSemi and Mentor Graphics (NASDAQ:MENT) today announced that the Pyxis? Custom Design environment, Eldo? simulator and Calibre? tools have been used in the design and verification of eoSemi's recently-announced ATOC? (Accurate Timing Oscillator Circuit) silicon oscillator products. ATOC (Accurate Timing Oscillator Circuit) oscillators are all-CMOS silicon replacements for quartz crystals. By saving space, increasing reliability and reducing costs, they allow

SiTime Corporation has shipped 100 million units of its MEMS devices, including oscillators, clock generators and resonators.

Ecliptek?s EMRE series of four surface-mount LVDS MEMS oscillators enable output frequency up to 625MHz with a frequency stability of ?20ppm.

IQD has launched a newly designed high-temperature clock oscillator. The new LHAT series is housed in a 7x5mm dual hermetically sealed ceramic package with gold plated kovar leads attached using a robust eutectic brazing process. The oscillators are capable of operating at temperatures from +25 to +200 degrees C. The LHAT series is available with a frequency range of 320kHz to 50MHz, a frequency stability of ±100ppm over +25 to +150 degrees C, and also ±175ppm over +25 to +200 degrees C for applications which need a higher temperature range. Operating at 3.3V this CMOS output clock oscillator can withstand a shock of 30,000g, 0.3ms. ½ sine and a vibration of 20g, 10-2,000Hz swept sine as per MIL-STD-202G Method 204D condition D. The unique method used to connect the leads to the package reduces the mechanical and thermal mounting stresses, making the LHAT series ideal for applications which are used in demanding mechanical and high thermal situations including: downhole instrumentation, rotary shaft sensors, underground mining tools and avionics applications.
