Clock buffers are integrated circuits designed to generate periodic signals for gap generation in electronic devices. The performance of clock buffers is characterized by minimal additive jitter, low output skew, and a wide operating temperature range.

The main types of clock buffers include differential clock buffers, single-ended clock buffers, universal types, and others. Differential output buffers are particularly critical for differential clock inputs, specifying key input level characteristics like the differential input voltage peak to peak or VICM (common mode voltage). The common mode voltage sets the voltage threshold between logic zero and logic one. These clock buffers find application across various industries, including military and defense, industrial settings, consumer electronics, and IT and telecommunication sectors, among others.North America was the largest region in the clock buffer market share in 2025.
