True Circuits has established close working relationships with many of the world‘s leading foundries and IDMs over the years. As the world-wide leader in timing circuit development and licensing, these silicon companies eagerly engage with True Circuits to ensure that our families of high-performance PLL and DLL IP are ported, silicon tested and readily available very early in the life of an advanced process technology to accelerate advanced chip development. The close technical relationships have allowed us to work collaboratively to ensure our circuits are optimally designed, characterized and correlated with foundry silicon. The close business relationships mean that our common customers can get early and easy access to both business and technical information about our timing technologies.
