Frequency synthesizers of various architectures, made possible by IC technology, are a key building blocks for applications which must accurately tune multiple channels, and hop from one frequency to another while using a single signal source such as a crystal oscillator. When you want to tune a desired radio station — AM or FM — […]

Low-noise OCXO features -182 dBc /Hz @100 kHz offset
Raltron Electronics Corporation announced the availability of a new ultra-low phase noise OCXO family featuring -182 dBc /Hz @100 kHz offset. Raltron’s new ultra-low phase noise OCXO series OXP8000 is available in standard frequencies of 10 MHz and 100 MHz with power supply voltages of 5V or 12V. The OXP8000 series OCXO offers integrated phase […]
Quartz crystals and oscillators, Part 1: Crystal basics
An oscillator or clock function is key to nearly all electronic circuits, and in most (but not all) cases, the heart of this oscillator circuit is a tiny piece of quartz, called the crystal blank or slab. It’s easy and commonplace to think of the crystal as a simple component, but as with most components, […]
Ultra-miniature fundamental quartz crystals hit 200 MHz
IQD has launched a range of quartz crystals which can operate in the fundamental mode up to 200 MHz. The quartz crystals are housed in a hermetically sealed 2.5 x 2.0 x 0.6mm (IQXC-152) and 2.0 x 1.6 x 0.5mm (IQXC-153) ceramic 4 pad package, 2 of the pads are grounded to the metal lid to improve […]

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 […]
