The C3-PLL-2 by Cologne Chip represents a novel digital approach to phase-locked loops (PLL), traditionally reliant on analog components. This core is tailored for frequency synthesis tasks, marking a departure from conventional methods by utilizing the DIGICC technology. The digital design lends the core adaptability across various digital CMOS processes without the need for additional external components like loop capacitors.
The standout characteristic of the C3-PLL-2 is its rapid lock time, which makes it remarkably efficient in applications where precise frequency locking is crucial. Furthermore, its fully digital architecture enables it to occupy less silicon space, offering a competitive advantage in terms of cost and design flexibility. By omitting external filters for supply voltages, the core simplifies integration into larger systems.
Designed to operate within a broad range of oscillator frequencies, the C3-PLL-2 ensures jitter comparable to its analog counterparts, while introducing the benefits of digital flexibility and reduced space requirements. Its inventive nature underscores Cologne Chip’s commitment to pioneering digital solutions in the semiconductor field.
