Description
General part information
CD74ACT297 Series
The CD74ACT297 provides a simple, cost-effective solution to high-accuracy, digital, phase-locked-loop applications. This device contains all the necessary circuits, with the exception of the divide-by-N counter, to build first-order phase-locked loops as shown in Figure 1.
Both exclusive-OR phase detectors (XORPDs) and edge-controlled (ECPD) phase detectors are provided for maximum flexibility.
Proper partitioning of the loop function, with many of the building blocks external to the package, makes it easy for the designer to incorporate ripple cancellation or to cascade to higher-order phase-locked loops.
