What is Holdover?
Posted: 20th May 2024
Holdover, in the context of oscillators, refers to the ability of an oscillator to maintain a clocks’ accuracy for a certain period when it temporarily loses its primary reference signal. This primary reference signal is typically provided by an external source, such as a GNSS satellite signal or another highly accurate clock source. When this reference signal is… Read More
CMOS vs HCMOS vs ACMOS – A History Lesson in Oscillators
Posted: 22nd January 2024
Unlocking the secrets of crystal oscillator technology, this blog aims to clarify the differences between CMOS, HCMOS, and ACMOS, unraveling the unique characteristics that make each a distinctive player in the world of electronic circuits. CMOS (Complementary Metal Oxide Semiconductor) first came about in 1963, and essentially replaced TTL Technology (Transistor… Read More
