PCIe Gen 4-compliant clock buffers powered from single 1.5 V/1.8 V supplies
Silicon Labs has introduced a new family of low-power PCI Express (PCIe) Gen 1/2/3/4 clock buffers that provide ultra-low jitter clock distribution in 1.5 V and 1.8 V applications. With additive jitter performance of 40 fs RMS (typical), Silicon Labs’ new Si532xx PCIe clock buffers provide more than 90 percent margin to stringent PCIe Gen 3 […]
Precise clock oscillators come in compact packages
Clock oscillators have become essential to digital equipment by providing the precisely timed reference signal that controls an electronic circuit. As electronic equipment development cycles grow continually shorter, demand for quick-delivery component samples continues to rise. Additionally, the trend toward smaller, more functional, better-performing electronic devices is also fueling demand for clock oscillators that offer […]
PLOs sport output frequencies to 6 GHz
Pasternack has unveiled a new line of phase -ocked oscillators (PLOs) that deliver accurate and stable output frequencies with low phase noise and spurious performance, making them ideal 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 […]
Low-power active mixer delivers 7-GHz bandwidth, 20 dBm OIP3
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 […]
