CD4046BCCW中文资料Micropower Phase-Locked Loop数据手册ONSEMI规格书

描述 Description

General Description
The CD4046BC micropower phase-locked loop (PLL) con sists of a low power, linear, voltage-controlled oscillator (VCO), a source follower, a zener diode, and two phase comparators. The two phase comparators have a common signal input and a common comparator input. The signal input can be directly coupled for a large voltage signal, or capacitively coupled to the self-biasing amplifier at the signal input for a small voltage signal.
