Depending on temperature range, the SiT7910 Super TCXO from SiTime can attain frequency stability of less than 0.1 ppm. Clock oscillator circuits serve two functions. They provide a clock timing signal for digital circuits such as microprocessors and they keep track of time, often for time-stamping of events. While oscillators for digital circuits typically produce […]

Evaluation board helps check out SMD oscillators, VCXOs, TCXO/VCTCXOs
The desire to be able to test oscillators quickly and easily is more than achievable using the IOSC EVBoard. The evaluation board is suitable for measuring most surface mount standard oscillators, VCXOs, or TCXO/VCTCXOs. It is available from IQD, part of the Würth Elektronik eiSos Group, and a selection of distributors. The IOSC EVBoard comes […]
The PC-board atomic clock, Part 1: Primary and secondary standards
Atomic clocks have shrunk from room-sized assemblies to PC-board mountable modules, admittedly with lower performance than their big siblings but still far better than crystal-based timing alternatives. Atomic clocks are based on the transitions of energy states of specific elements such as cesium, ytterbium, rubidium, and others under specific and tightly controlled conditions. They are […]
Crystal oscillators provide space-qualified alternatives for devices with long lead times
Q-Tech Corporation announces the availability of extensive in-stock availability of full space-qualified and B-level quartz crystal oscillators in a variety of traditional and ultra-miniature packages. The immediate availability of these components may alleviate supply chain problems delaying production of space, military, avionics and high-temperature applications requiring fully tested and certified devices. In addition, a large […]

Designers can now achieve double the battery life together with robust protection and highest accuracy for the internet of things (IoT), industrial and healthcare applications with three new Essential Analog ICs from Maxim Integrated Products, Inc.: MAX41400 instrumentation amplifier, MAX40108 precision operational amplifier, and MAX31343 real-time clock (RTC) with integrated MEMS oscillator. When designing IoT and battery-operated sensors, engineers […]
RTC module offers high accuracy across industrial temperature range
Micro Crystal introduces the new RV-3032-C7 Real-Time Clock (RTC) Module, which offers the world’s best time accuracy across industrial temperature range at ultra-low current consumption. This high-performance ultra-compact RTC Module, featuring a custom IC and integrated quartz crystal resonator, sets new standards in the smallest size (half of the footprint of a uSOP-8 package, no […]
Smallest SMD oven-controlled crystal oscillator hits 40 MHz
Raltron has designed the smallest SMD oven controlled crystal oscillator (OCXO) available on the market. At only 9 mm x 7 mm, the OX7000 Series is designed for applications that require ultra-small size and superior temperature stability. This includes all aspects of 5G wireless infrastructure, transmission, precision instrumentation, broadcasting, utility metering infrastructure, and more. The […]
TCXOs for Silicon Lab ICs target network synchronizer, base station apps
Sunstu Electronics introduces the latest Stratum 3 TCXO specially designed for Silicon Lab ICs. These TCXOs come in small, ceramic SMD package delivered by Tape and Reel. The Stratum 3 clock serves to track input under normal operating conditions, but at a wider range than the Stratum 2. STX478 and STX479 both come in a […]
Ultra-low-jitter clock oscillators target high-frequency DSPs in optical apps
Raltron has launched an ultra-low-jitter clock oscillator family suitable for high-frequency digital signal processors (DSPs) in optical applications. The CL2520 LVDS clock oscillator series is designed to support optical modules commonly used in networking and data center applications. These include quad small form-factor pluggable (QSFP), octal small form-factor pluggable (OSFP), and C form-factor pluggable 2 […]
LVDS oscillator boasts super-low phase jitter
For high-speed data transfer applications (transceiver or clock distribution) that require a high data rate, introducing our new LVDS Oscillator. Casey Conlan, Suntsu’s CEO enthused, “our high-speed networking customers will be clamoring to get their hands on this part!” The SUO75L Series Oscillator is designed with a third overtone crystal and a frequency range of […]
