CD74HCT7046A 带 VCO 和锁定检测器的高速 CMOS 逻辑锁相环

The CD74HCT7046A 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.

The length of the up/down K counter is digitally programmable according to the K-counter function table
