Analog Devices announces the LTC5562, a low power, high performance active double-balanced mixer, capable of 50Ω matching over a very wide frequency range of 30MHz to 7GHz. This versatile mixer can be used in either frequency upconversion or downconversion applications, with outstanding conversion gain of 2dB. The device runs on a single 3.3V supply rail, drawing 40mA […]

Phase-locked oscillators cover output frequencies between 50 MHz to 6000 MHz
A new line of phase-locked oscillators (PLO) deliver accurate and stable output frequencies with low phase noise and spurious performance, making them candidates for use in radar and other exciter or frequency generation applications. Typical applications include phase-locked loops, frequency synthesizers function generators and as a local oscillator source in receiver and transmitter stages. Pasternack’s […]
Stable phase-lock oscillators operate from 500 MHz to 6 GHz
Fairview Microwave Inc., a supplier of on-demand microwave and RF components, has launched a new line of phase locked oscillators (PLO) that are accurate and stable frequency sources and a key component for almost any communications, navigation, surveillance or test and measurement system. These PLOs offer accurate and stable output frequencies with low phase noise […]

Mechanical vibration for electronics: the quartz crystal
It is now 100 years since Alexander Nicholson at Bell Telephone Laboratories built and patented the first crystal oscillator, and crystals are still the main source of accurate oscillations up to UHF frequencies using quartz instead of Rochelle Salt (see US patent 2212845). Quartz crystal oscillators use the piezoelectric effect. The piezoelectric effect refers to […]

Low-jitter, low-power clock chips target coin-cell battery operated IoT sensors
SiTime Corporation introduced the SiT1569 oscillator and SiT1576 Super-TCXO with expanded frequency range. These unique timing solutions, available in a tiny CSP (chip-scale package), enable coin-cell battery operated IoT sensors to run up to 10 years. By using SiTime’s revolutionary TempFlat™ MEMS and mixed-signal technology, these devices deliver increased timekeeping accuracy and system power savings. The ultra-reliable, low-jitter SiT1576 and […]

Free-running reference oscillators span 10 MHz to 100 MHz with low phase noise
Pasternack has released six new free-running reference oscillators that generate a highly stable and accurate output frequency response with low phase noise and spurious performance levels, making them ideal in phase locked loops, function generators, frequency synthesizers and receivers for communication, radar, navigation, surveillance and test and measurement applications. These free-running, fixed-tuned oscillators use a high-stability […]
What is a clock and what are its critical parameters (Part 2)?
The performance of a clock function, which includes the crystal and associated circuitry, is defined by parameters which are measured over both the short term and long term. It is also characterized by change in specifications due to temperature variations, aging, and mechanical considerations such as vibration and shock. How is clock performance defined? Both […]
