Compared to the ordinary PLL circuits, it can endure the short time appearance that occurs once in a horizontal line of the sync signal. It can adapt to the phase alternation character of a PAL video signal and recognize the phase alternation line. The local color sub-carrier can be generated for synchronous demodulation by the circuit.

该电路使用了全数字锁相环对色同步信号进行跟踪，与普通锁相环电路相比，它不仅能适应制视频信号中色同步信号每行出现一次和PAL制信号逐行倒相的特性，还能识别倒相开关信号，准确地产生本地色副载波用于同步解调。
