CD74ACT297 DIGITAL PHASE-LOCKED LOOP

ordering information 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.
