Clock oscillator remains stable when powered from varying battery voltage

October 27, 2020 By Redding Traiger

IQD Frequency Products is pleased to launch its newest standard packaged clock oscillator series, the IQXO 951, which operates with a supply voltage range from 1.6 V to 3.3 V. Many of today’s industrial and consumer applications require batteries as a power source. Therefore, products need to handle a change in voltage as the battery discharges. This can lead to design issues when using a standard oscillator with a fixed supply voltage. A discharging battery may cause a decrease in the source voltage, which consequently changes the frequency of the oscillator. Following this, the timing accuracy within the application will decline.

The IQXO-951 is available in industry-standard packages of 3.2 x 2.5 mm, 2.5 x 2.0 mm and 2.0 x 1.6 mm. It will allow electronic equipment manufacturers to benefit from standard stability of ± 25 ppm over the industrial temperature range from -40 to 85 degrees C. Moreover, parts are also available with an extended temperature range up to -40 to 125 degrees C.

The new clock oscillators are suitable for most applications that are designed for battery-powered products. In addition, customers could reduce their BOM management by using a single part instead of multiple oscillators with fixed supply voltages. Common markets for these applications are Telecommunications, IoT, Communication, medical, and many others.

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
