CD74ACT297 - DIGITAL PHASE-LOCKED LOOP

General Description

/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 exclusive-OR phase detectors (XORPDs) and edge-controlled (ECPD) phase detectors are provided for maximum flexibility.
