Synthesized tuning, Part 2: Advanced synthesizers and performance
Part 1 of this FAQ looked at the basic issues and topologies related to the challenge of frequency synthesis. Part 2 continues with advanced approaches and their attributes, as well as general concerns when choosing a synthesizer. Q: Are there other digitally-controlled synthesizer topologies? A: Yes. A widely used one is called the classical phase […]
Synthesized tuning, Part 1: Basic frequency-synthesizer principles
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 — […]

MEMS OCXO enables 5G equipment to be deployed anywhere, in any environment
SiTime Corporation announced the Emerald Platform, a revolutionary precision timing solution that solves critical timing challenges for 5G infrastructure equipment. With the Emerald Platform, operators can deploy 5G equipment in harsh environments and reliably offer mission-critical services. “Timing is potentially the single biggest point of failure in 5G systems and can impact performance, reliability, and revenue. […]
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 […]
