CEVA recognizes that not all requirements can be covered by a set of application specific or compiler generated PLLs. We specialize in offering those custom modifications that can sometimes make your design more flexible and efficient. Whether they are minor modifications or major design changes our skilled design team has the experience and knowledge to interpret your requirements and deliver the highest quality solutions. Examples of prior customizations include:-

The addition of mux logic to allow PLL outputs to be selected in specific sets
Non integer output dividers such as 1.5 and 2.5 ratios
The addition of range bits enabling multi-octave VCO capability
Bandwidth customization to compensate for excess input jitter
Multi-phase VCO outputs
