微功耗锁相环 Micropower Phase-Locked Loop
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.
Features
■ Wide supply voltage range: 3.0V to 18V
■ Low dynamic power consumption: 70 µW typ. at fo = 10 kHz, VDD = 5V
■ VCO frequency: 1.3 MHz typ. at VDD = 10V
■ Low frequency drift: 0.06%/°C at VDD = 10V with temperature
■ High VCO linearity: 1% typ.
Applications
• FM demodulator and modulator
• Frequency synthesis and multiplication
• Frequency discrimination
• Data synchronization and conditioning
• Voltage-to-frequency conversion
• Tone decoding
• FSK modulation
• Motor speed control
