Business Model

TCI currently licenses its PLL, DLL and DDR PHY IP directly to customers and receives licensing fees for the design and integration services. Licensing terms are very attractive and do not require royalty payments. In addition, TCI has partnerships with other semiconductor companies that provide indirect sales channels for its licensed products. All TCI products are designed and packaged in a way that makes it possible for customers to easily choose and integrate a design that meets their specific needs.

Technology Evaluation

Customers who are interested in licensing TCI's PLL, DLL and DDR PHY IP should download TCI's standard Mutual Non-Disclosure Agreement (NDA), have it signed by a manager at the director level or above, and e-mail back a PDF version to

The NDA specifies the terms and conditions to which a customer must agree in order to obtain access to detailed TCI product specifications via the Products section of this website.

When the signed NDA is received by TCI, it will be reviewed for completeness and the signer will be independently verified, usually on the same day. If the NDA is complete, TCI will email back a counter-signed PDF version and an account ID and password which will allow complete access to TCI product specifications.


TCI is the sole owner of the intellectual property on which all TCI PLL, DLL and DDR PHY designs are based. Customers that want to license TCI's PLL and DLL hard macros should complete the NDA filing process and contact TCI Sales at (650) 949-3400 or to obtain pricing information and specific licensing terms.
