产品描述

CD4046B CMOS Micropower Phase-Locked Loop (PLL) consists of a low-power, linear voltage-controlled oscillator (VCO) and two different phase comparators having a common signal-input amplifier and a common comparator input. A 5.2-V zener diode is provided for supply regulation if necessary.

The CD4046B types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

产品特性

Very low power consumption: 70 µW (typ.) at VCO fo = 10 kHz, VDD = 5 V
Operating frequency range up to 1.4 MHz (typ.) at VDD = 10 V, RI = 5 k
Low frequency drift: 0.04%/°C (typ.) at VDD = 10 V
Choice of two phase comparators:
- Exclusive-OR network (I)
- Edge-controlled memory network with phase-pulse output for lock indication (II)
High VCO linearity: <1% (typ.) at VDD = 10 V
VCO inhibit control for ON-OFF keying and ultra-low standby power consumption
Source-follower output of VCO control input (Demod. output)
Zener diode to assist supply regulation
Standardized, symmetrical output characteristics
100% tested for quiescent current at 20 V
5-V, 10-V, and 15-V parametric ratings
Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"
Applications
- FM demodulator and modulator
- Frequency synthesis and multiplication
